Question

Angle 1 and angle 2 are complementary angle and angle 2 and angle 3 are supplementary angle. If angle 1 =45 find the measure of angle 3....

Answer 1

Answer:

180 is the answer of question

Answer 2

Answer:

Ok,

<1 and <2 are complementary.

So, <1+<2= 90°= A

<2 and <3 are supplementary angles.

<2+<3= 180°= B

Now, we are given that <1 = 45°

Substitute the value in A

45°+<2= 90°

<2= 90°- 45°

<2 = 45°

Now, Substitute the value of <2 in

= B

<2+<3 = 180°

45°+<3= 180°

<3= 180°-45°

<3= 135°
