Question

y-20° and y+30° are the measures of complementary angles. find the measure of each angle​

Answer 1

Answer:

Here is the answer:

Step-by-step explanation:

Note- As complementary angle are those whose sum is 90°

Therefore y-20°+y+30°=90°

2y+10°=90°

2y=80°

y=40°

So y-20°=20° and y+30°=70°

Answer 2

$\huge\bold\green{ solution }$

the measurement of complementary angle is =90°

$y - 20 + y + 30 = 90 \\ \\ 2y = 90 - 10 \\ \\2y = 80 \\ \\ y = \frac{80}{2} \\ \\ y = 40$

now y=40 put in equation

$y - 20 \\ \\ 40 - 20 = 20$

equation 2

$y + 30 \\ \\ 40 + 30 = 70$

angle of complementary is 20° and 70°
