If the measure of angle 3 is equal to (2x + 6)° and x = 7, which statements are true? Check all that apply. 3 lines intersect to form 6 angles. From top left, clockwise, the angles are 1 (90 degrees), 2, 3, 4, 5, 6.

The measure of angle 6 is 20°.

The measure of angle 5 is 70°.

The measure of angle 2 is 80°.

Angles 2 and 5 are complementary.

Angles 5 and 6 are supplementary.

Angles 1 and 4 are supplementary.

The answers are

A. The measure of angle 6 is 20"

B. The measure of angle 5 is 70"

F. Angles 1 and 4 are supplementary

Hope this Helps!

To answer this we will add, but before we add we will change 4/5 in to a decimal. to change ANY fraction into a decimal we have to divide the numerator by the denominator. lets do it:- 

4/5 
4 ÷ 5 = 0.8

Now lets substitute 0.8 for 4/5 and then add.

4/5 + 0.05
0.8 + 0.05 = 0.85

CHECK OUR WORK:-

0.85 - 0.8 = 0.05
We were RIGHT!!

So, the decimal 0.85 is equivalent to 4/5 + 0.05.

Hope I helped ya!! xD
