Question

7. Find x if two angles of measures (x +10) and (x - 30) are
(1) complementary to each other.
(11) supplementary to each other,​

Answer 1

Answer: Hope It Helps You.

Step-by-step explanation:

let complementary angles =90

then,

( x+10°) +(x-30°) = 90°

x+10+x-30=90

2x-20=90

2x=90+20

2x= 110

x=110÷2

x=55

now,

x+10= 55+10=65

x-30= 55-30=25

let supplementary angles =180

then,

x+10+x-30 =180

2x -20 = 180

2x= 180+20

2x=200

x=200÷2

x=100

now,

x+10=100+10 = 110

x-30=100-30 = 70
