∠A and ∠B are complementary angles. The measure of ∠A is twice the measure of ∠B.
Write and equation to represent the complementary angle relationship between ∠A and ∠B. Use the equation to find the measure of ∠A and ∠B. Show all of your work.

A + B = 90

A = 60°

B = 30°

Step-by-step explanation:

A + B = 90

A = 2B

2B + B = 90

3B = 90

B = 30

A = 2B = 2(30)

A = 60°

Step-by-step explanation:

<A + <B = 90 °

<A = 2 <B

2<B + <B = 90°

3 <B = 90°

<B = 90° / 3

= 30°

<A = 2<B

<A = 2 × 30°

= 60°

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
