Question

69. If mZA = 70°, what is the measure of the supplement of the
complement of ZA?​

Answer 1

Answer:

The correct answer is 160°

Step-by-step explanation:

First of all we have to find out the complement of ZA

Now let the complement of ZA be 'x'

x+ZA=90°

x+70°=90°

x=90°-70°

x=20°

Now we have to find out the supplement of complement of ZA

We have complement of ZA i.e 20°

Now,we have to find its supplement

Let its supplement be 'y'

Now,

y+20°=180°

y=180°-20°

y=160°

Answer 2

Answer:

∠A=160°

Step-by-step explanation:

Let the measure of the complementary angle be "a"

70+a=90

a=90-70

∴a=20°

Let the measure of the supplementary angle of 20°be "x"

20+x=180°

x=180-20

∴x=160°

Hence,

The measure of the supplement of the compliment of ∠A is 160°
