Question

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

Answer 1

Answer:

see explanation

Step-by-step 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 )
