Question

Use the three steps to solve the problem.

One of two complementary angles is 4 more than the other. Find the angles.
(Recall that complementary angles are angles whose sum is equal to 90 .)

Answer 1

complementary angles add up to 90

Answer 2

so, if we let one angle =x,
other angle = x+4

Answer 3

step 1 : solve for x

Answer 4

86

Answer 5

correct !

x = 86

Answer 6

wait a sec, did we get x=86 ?

Answer 7

x + x + 4 = 90

2x + 4 = 90

2x = 86
x = ?

Answer 8

yes

Answer 9

x + x + 4 = 90

2x + 4 = 90

2x = 86
x = 86/2
= ?

Answer 10

43

Answer 11

thanks god !

Answer 12

:)

Answer 13

thats step 1,

Answer 14

step 2 : first angle = x = 43

Answer 15

step 3 : second angle = x+4 = ?

Answer 16

47
