Answer 2

Given

• Figure 2.7
• Line l || m
• Line p || n

____________________________

To Find

• The measure of ∠a, ∠b and ∠c .

Solution

[View the attachment for the figure.]

Here the value of ∠x is 45° because it is the corresponding angle.

We know that the sum of linear pairs is 180, so -:

➵∠x + ∠b = 180°

➵∠45 + ∠b = 180°

➵∠b = 180°- 45°

➵∠b = 135°

Since ∠b is vertically opposite to ∠b, they will have the same value.

➵∠a = ∠b

➵∠a = 135°

Since ∠c is vertically opposite to ∠a, it will have the same value of that of ∠a.

➵∠c = ∠a

➵∠c = 135°

∴ ∠a = 135°

∴ ∠b = 135°

∴ ∠c = 135°
