Answer 1

Answer:

2.1 abp = 67°

2.2y. = 20°

2.3 d is not true

2.4a = 32

pls Mark me as brainlist

Answer 2

Step-by-step explanation:

1. 67°

because given an angle of 46 degree and it seems a linear the measure of a linear pair is 180 degree and if we will

X +X +46=180

2x+46=180

2x=180-46

2x=134

X=134/2

x=67

2.

=y+2y+6y=180

=3y+6y=180

=9y=180

=y=180/9

=y=20

3. all are 90 degree because there are linear pairs and measure of a linear pair is 180 degree

and the given angles are equal.

so,

<a=<d

and the measure of vertically opposite angles is same so,

<a=<b

<d=<c

so, 90°

4. on the linear pair 30 degree + x = 180

so the he measure of X will be 150

and due to vertically opposite angels

angle <axy equals to < zxb (30)

<yxb=<axz (150)

I tried my best but I don't know no.5,6

hope it helps
