We first have to find 2 pairs of sides that proportional.

35/20=42/24=7/4

and 21/b should be 7/4 as well because if we want the triangles to be similar the sides should be in proportion.

21/b=7/4

84=7b

b=12

Done!

Hope this helped, any questions about this just ask in the comments and I will answer.

The answer is D. 44 degrees.


It’s not A because that would mean the angle is over 90 and it’s not because you can see that it’s smaller than a right angle.


It’s not B because that would mean it’s a bit smaller than a right angle but it’s a lot smaller.


It’s not C because that wound mean the angle is about a 90 degrees right angle but it’s not.


D is the most reasonable answer.

Hope this helps! :)
