Question

In the diagram a II b, use the diagram to answer the question. if m∠6=21, what is m∠4?

Answer 1

`\\ \tt\hookrightarrow m<6+m<8=180`

`\\ \tt\hookrightarrow 21+m<8=180`

`\\ \tt\hookrightarrow m<8=180-21`

`\\ \tt\hookrightarrow m<8=159`

Now

• m<4 and m<8 are corresponding angles
• m<4=m<8=159°

Answer 2

`m< 6+ m< 8 = 180`

`21+ m < 8 = 180`

`m<8 = 180- 21`

`m<8 = 159`

So,

`m<4` and
`m < 8` [corresponding angles]

`m<4=m<8=159°`
