In a triangle, Angle B is twice as large as Angle A. Angle C is five more than

Angle B. Write and solve an equation to find the measure of Angle A.

Answers

Answer:

<A = 35 degrees

Step-by-step explanation:

<A = x

<B = 2x

<C = 2x + 5

X + 2x + 2x + 5 = 180 degrees

5x + 5 = 180

5x = 180 -5

x = 175/5

x = 35

Robinson's tapestries all measure 1.5m x 1m wide. Express the proportion of the tapestries' height to width using whole numbers
and ratio notation.

Answers

The proportion of the tapestries' height to width using whole numbers is 3:2

proportions are expressed as the ratio ratio two integers. For instance  a/b is the ratio of a to b

Given the following sides it a tapestries

Width = 1m

Height = 1.5m

Taking the ratio of the height to the width is expressed as;

Ratio = 1.5 : 1

Writing as a fraction

Ratio = 1.5/1

Ratio = 1.5

Comparison operators are operators that compare values. For example >, <, ≥, ≤, ≠ etc.

Therefore,

5 + 9 - 2³ = 14 - 2³ = 14 - 8 = 64²- 6 = 16 - 6 = 10

The measure of an angle is 6 greater than half the measure of it’s supplement. Find the measure of the angle

Answers

Answer:

64°

Step-by-step explanation:

Set the measure of the original angle as x.

The measure of its supplement would be 180-x.

Thus,

x = 0.5 * (180-x) + 6

x = 90 - 0.5x + 6

1.5x = 96

x = 64°

The measure of angle is 64 degree.

What is Algebra?

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:

The measure of an angle is 6 greater than half the measure of it’s supplement.

let the angle be x

supplement of x= 180- x

and,  6 greater than half the measure of it’s supplement.

x = 6 + 1/2( 180- x)

x= 6 + 90 - x/2

x+ x/2 = 96

3x/2 = 96

x= 32 x 2

x= 64

Hence, the measure of angle is 64 degree.

Tan 0 = 21/29

Step-by-step explanation:

Use the identity sin(2θ) = 2sin(θ)cos(θ)  

You have sin(θ) = 20/29

Given that θ is acute (meaning it's in the first quadrant), and, the opposite side is 20 and the hypotenuse is 29, you can calculate the adjacent side with the Pythagorean Theorem as 21. That means the cos(θ) = 21/29.

So sin(2θ) = 2(20/29) = (21/29)
