Chapter 3: Q14. CR (page 111)

If m鈭�1=30and m鈭�4=130 thenm鈭�2=?

Short Answer

Expert verified

The measure of鈭�2 is 100.

Step by step solution

01

Step 1. Highlight ∠1, ∠2 and ∠4.

02

Step 2. Apply exterior angle theorem.

The measure of an exterior angle is equal to the sum of measure of two remote interior angles.

03

Step 3. Description of step.

From the figure it can be observed that鈭�1,鈭�2 are remote interior angles鈭�4and is exterior angle then by exterior angle theorem,

m鈭�1+m鈭�2=m鈭�430+m鈭�2=130m鈭�2=130鈭�30=100

Therefore, the measure of鈭�2 is 100.
