Can only like terms be combined?​

Answer:

4.2 ft

Step-by-step explanation:

Reference angle = 77°

Opposite side = DE = x

Hypotenuse = CD = 4.3 ft

Apply the trigonometric function of sine. Thus:

Sin 77 = opp/hyp

Sin 77 = x/4.3

Multiply both sides by 4.3

4.3 × sin 77 = x

x = 4.2 ft (nearest tenth)

Answer:

m<4= 119

m<5= 119

m<6= 61

m<7= 119

Answer:

45, 45 and 90 degrees

Step-by-step explanation:

Complete question

The measures of angles X and Y are the same, x degrees. The measure of angle Z is twice the measure of angle Y. Find the measure of each angle

Let the sum of the angles be 180 degrees

X = x

Y = x

If Z is twice the measure of angle Y, then;

Z = 2x

Taking the sum

<X + <Y + <Z = 180

x+x+2x = 180

4x = 180

x = 180/4

x = 45

since Z = 2z

Z = 2*45

Z = 90

Hence the measure of the angles X, Y and Z are 45, 45 and 90 respectively

Answer:

y = 1.25 and/or 1 1/4

Step-by-step explanation:

Substitute 2 for x in the equation.

4y = 5(2-1)

4y = 5(1)

4y = 5

Divide 5 by 4 to isolate the variable.

y = 1.25 and/or 1 1/4

Answer:

c must be less than 10 but greater than 4.

Step-by-step explanation:

In order to solve this problem, you have to apply the triangle inequality theorem. This theorem is used to determine whether or not you can form a triangle. According to the theorem, the sum of the two sides must be greater than the longest side of the triangle.

For instance, a triangle has side lengths 4, 5, and 7.

Can you form a triangle with these values?

Well, let's see

Since 4 and 5 are values less than 7, you are going to be adding those numbers. 4 plus 5 is 9. 9 is greater than 7. This means that you can form a triangle with those numbers.

For this question, you are given a triangle that has the side lengths of 3 inches, 7 inches, and c inches. The question wants the range of values. Make c the shortest side and the longest side.

Let's start with longest first.

take 3 and 7

Add them and you will get 10.

10 is greater than c. or c<10.

For the shortest side make 7 the longest

3 plus c is less than 7

subtract 3 from both sides

then you get c is less than 4. or c<4.

So you have c<4 and c>10.

combine them to make a long inequality.

4<c<10.

That is your answer.

Answer:

21> 2x+ 15

Step-by-step explanation:

The expression is 21 > 15+ 2x

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Twenty-one is greater than the sum of fifteen and two times a number​

let the number be x.

two times a number​ = 2x

and, sum of fifteen and two times a number​ = 15 + 2x

So, Twenty-one is greater than the sum of fifteen and two times a number​

21 > 15+ 2x

Hence, the expression is 21 > 15+ 2x.

Answer:

885.18

Step-by-step explanation:

Base = 18x18=324

triangles = 1/2(18)height

To find the height, you could divide it in half and use the 30-60-90 rule or Pythagorean theorem.

9²+b²=18²

81+b²=324

b²=324-81

b²=243

b=√243

b=15.58

So each triangle is 1/2(18)(15.58845)=140.2961.

Four of them would be 561.1845.

Now add the base.

561.1845+324=885.1844

Step-by-step explanation:

*NOTE* - 0.16666 is equavilent to 1/6

We can use the sum of fractions to write out the decimal:

We can see that 0.16666...is the fraction 1/6 therefore the decimal is

2.16666...= 2 + 1/6 = 13/6

Given :

M(6,5) is the mid-point of the straight line joining A(2 , 3) to the

point B.

To Find :

The coordinates of B.

Solution :

Let, coordinates of point B is ( h , k ) .

It is given that M is the mid - point of the straight line joining points A and B.

Coordinates of M is given by :

[tex]M = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\(6,5 ) = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\\dfrac{2+h}{2} = 6 \ , \ \dfrac{3+k}{2} = 5\\\\h = 10 \ ,\ k = 7[/tex]

Therefore, coordinates of point B is ( 10 , 7 ).

For question 1 and 2, you should keep in mind that the sum of all angles in a triangle is 180°. 1. If the measure of one angle of a triangle is 90 degrees, you can assume that the sum of the other two triangles should be 90 degrees. Because

180 - 90 = 90

The sum of the three angles of any triangle is equal to 180 degrees.

Angle 2=127 because 180-53=127.

Angle 3=23 because 180-30-127=53

Angle 1=37 because 90-53=37

Angle 4=90

Angle 1+4=127

The measure of ∠1 is 125° .

Next x+64=110. The reason why you can do this is because ∠R is going to be an opposite interior angle. Subtract 64 from the left and right sides. x=46
