Chapter 3: Q10 (page 80)

If m∠1=130what are the measures of the other numbered angels?

Short Answer

Expert verified

Measures of numbered angles are

m∠2=50;m∠3=50;m∠4=130;m∠5=130;m∠6=50;m∠7=50;andm∠8=130

Step by step solution

01

Step 1. Observations from figure

  • Arrowheads are shown on lines Iand P, so these lines are parallel
  • Line tis transversal to the parallel lines IandP
02

Step 2. Find m angle 2

∠1and ∠2forms linear pair, so sum of these angles is 180

m∠1+m∠2=180130+m∠2=180

m∠2=180−130

03

Step 3. Find m angle 3

∠2 and ∠3are vertically opposite angles, so there values are equal

m∠3=m∠2

Thus,m∠3=50

04

Step 4. Find m angle 4

∠1and ∠4are vertically opposite angles, so there values are equal

m∠4=m∠1

Thus,m∠4=130

05

Step 5. Find m angle 5, m angle 6, m angle 7, and m angle 8

Since, corresponding angles are equal

Pair of corresponding angles are

∠1−∠5,∠2−∠6,∠3−∠7,and∠4−∠8

Thus, measurement of these angles are

m∠5=130m∠6=50m∠7=50m∠8=130
