Question

What are the values of a,b,c,and d

Answer 1

see explanation

Explanation:

Given that
`l_(1)` and
`l_(2)` are parallel lines then

a = 35 ( alternate angle )

The sum of the angles in a triangle = 180°, thus

b = 180 - (90 + a) = 180 - (90 + 35) = 180 - 125 = 55

b and c form a straight angle, thus

c = 180 - b = 180 - 55 = 125

d = 55 ( alternate to b )
