Answer 1

Answer:

X= 21

Step-by-step explanation:

First divide 105 by 5,

Then ans will be 21

then you can varify

3x= 63

4x= 42

63+42=105

hence it is proved

plsss mark me as brainliest

thanks

Answer 2

Answer:

x=21°

Step-by-step explanation:

AB || CD

Thus ∠CPQ =∠ AQR ( They are corresponding angles)

so3x+2x=105

5x=105

x=105/5

=21°
