The angle of a a triangle is 180 so you do
180 - 44 = 136
136 - 31 = 105
so y = 105
Yes - they have to be similar. Since they are using the same line as the hypotenuse, the ratio of the other two sides are in the same ratio (ie, the slope of the line), the 3 inner angles will be the same. Thus, the triangles will be similar.
Hey there! :D

The only thing you can simplify is 7 and 3.
7-3= 4
2x+4 <=== simplified expression

Answer:
31°
3
108°
Step-by-step explanation:
The measure of angle ADB is congruent to the measure of angle CBD, so it is equal to 31°.
4x = 12
divide by 4 on both sides and you are left with x=3
angle A is congruent to angle C, so it is equal to 108°.
Hope this helps!
