please tell me solution of this 2 questins with solved stataemnt

Answer 1

answer to question no.7

the the two angles be x an 8x

complementary angles add up to 90

x+8x=90
9x=90
x=90/9
x=10
8x=80

the angles are 10 an 80

answer to question no. 8

angle1=(2x-10)
angle2=(x-5)

complementary angles add up to 90

2x-10+x-5=90
3x-15=90
3x=90+15
3x=105
x=105/3
x=35

angle1= 2×35-10
= 60
angle2= 35-5
=30


hope it helps
