Answers
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

Write your answer in the space below.
Answers
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

Factor the polynomial: b2−12b+36
Answers
•You have to find two numbers that multiply to make the last number (36) and add up to the second number (-12b).
•Since the last number in the equation (36) is positive, and the second number in the equation (-12b) is negative, you know that you will have to multiply two negative numbers to get 36, because the two numbers have to add to -12.
So when looking at factors of 36 -
1, 36
2, 18
3, 12
4, 9
6, 6
Looking here, 6 and 6 would be the most to be the answer.
You turn these negative and =
-6 x -6 = 36
-6 + -6 = -12
Answer: (x - 6) (x - 6) or (x - 6)^2

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

The amount of change you will receive after buying the cloth is N3.00.
What is function? Differentiate between equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that you bought 4m of cloth at N1.75 per meter.
The amount of change you will receive after buying the cloth is -
N10 - N(1.75 x 4)
N{10 - 1.75 x 4}
N{10 - 7}
N3.00
Therefore, the amount of change you will receive after buying the cloth is N3.00.

The third side of the right triangle is 10.72 unit.
What is Pythagoras theorem?Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides.
Given, the side of right triangle is;
Let H be hypotenuse = 14
And P be perpendicular = 9
Then to find third side base be B,
we use the Pythagoras theorem;
(H)² = (P)²+(B)²
Rearranging,
(B)² = (H)² - (P)²
(B)² = (14)² - (9)²
(B)² = 196 - 81
(B)² = 115
B = 10.72 unit.
Therefore, the third side is 10.72 unit.
