Question

two complementary angle are (5x+13) and (2x+7) find them​

Answer 1

Answer:

sum of complementary angles is 90

$5x + 13 + 2x + 7 = 90 \\ 7x + 20 = 90 \\ 7x = 90 - 20 \\ x = \frac{70}{7} \\ x = 10 \\ \\ so \: the \: first \: angle \: is \: = 5x + 13 = 63\\ second \: = 2x + 7 = 27$

Answer 2

Answer:

The two complementary angles are 63° & 27°

Step-by-step explanation:

we know that complementary angles forms 90°

5x+13°+2x+7° = 90°

7x+20° = 90°

7x = 90°-20°

7x = 70°

x = 70°/7

x = 10°

then, 5x+13 = 5(10°)+13 = 50°+13 = 63°

2x+7 = 2(10°)+7 = 20°+7 = 27°
