Um.Answer with step by step explanation? :)

Step-by-step explanation:

c )

Sum of all angles on a straight line is 180° so,

3x - 30 + 2x + 30 = 180

5x = 180

x = 180/5

x = 36

so,

value of x is 36

therefore, 3x - 30 = 3(36) - 30 = 108 - 30 = 78°

also we know,

2y = 78° ( Vertically opposite angle )

so,

2y = 78

y = 78/2 = 39°

hence, x = 36° and y = 39°

d )

sum of all angles on a straight line is 180°

so,

we know,

2x/3+1

2(174)/3 + 1

348/3 + 1

116 + 1 = 117

now,

3y + 2 = 117 ( vertically opposite angle)

3y = 117 - 2 = 115

y = 115/3 = 38.3°

hence, x = 174 and y = 38.3.

hope this answer helps you dear...take care and may u have a great day ahead!
