Question

Two complementary angles are (x+16) and (3x-4), then find the value of x.​

Answer 1

Answer:

19.4

Step-by-step explanation:

sum of complementary angoes=90 degree

so, x+16+3x-4=90

4x+12=90

x=19.4

Answer 2

Answer:

complementary angles measures 90*

(x+16) + (3x-4)=90

x+16+3x-4= 90

(x+3x) + (16-4) = 90

4x + 12 = 90

4x = 90- 12

4x = 78

x = 78/4
