Answer and Step-by-step explanation:
Answer is in picture.
We solve for the hypotenuse of the bottom triangle before solving for x.
We have to use the trigonometric functions of Cosine and Tangent.

Answer:
x=-7
Step-by-step explanation:
x-y=-10
x=-10+y
(-10+y)-6y=-25
-10+y-6y=-25
-5y=-15
y=3
x-3=-10
x=-7
Angles 1, 3, and 4 make up a straight line.
Thus, 3x + 90 + 3x - 6 = 180 (angle sum of straight line)
6x - 6 = 90
6x = 96
x = 16
Now angle 1 becomes 3(16) = 48
Angle 1, 2, and 3 also make up a straight line.
Thus, angle 2 + 48 + 90 = 180
angle 2 + 138 = 180
angle 2, therefore, becomes 42. In essence, (A)

Answer:
41
Step-by-step explanation:
Applying Pythagoras theorem since it is a right angled triangle.
(Hypotenuse)^2=(base)^2+(perp)^2
Hyp^2=(9)^2+(40)^2
Hyp^2=81+1600
Hyp^2=1681
Taking sq root on both sides
Hypotenuse=41
