in 1st figure

2:1=(x+2):2

2/1=(x+2)/2

4=x+2

x=2.

Similarly in the 2nd figure

8:5=(8+3):(5+x)

8/5 = 11/ (5+x)

8(5+x) =55

40+8x=55

8x=15

x=15/8

x=1.875

Help pls asap!!!!! !!!!!

Answer:

It is 40 degrees.

Step-by-step explanation:

You can start off by understanding this is not a right angle (exactly 90 degrees, think of a corner of a room) or and obtuse angle (more than 90 degrees, bigger than a right angle). With that information we know that it is an acute angle (less than 90 degrees, smaller than a right angle). With that we have 40 and 50 degrees left. When you compare the angle with the 40 degrees one, it is the same size. The angle 1 is a reflection of the triangle with the 40 degrees angle. Hope this helps :)
