Answer:
140°
Step-by-step explanation:
The other angle inside is 40 so 180-40 is 140°
Hello from MrBillDoesMath!
Answer:
pi/2, - 3pi/2
Discussion:
The solutions of sin(t) = 1 are (pi/2) + 2*pi*n, where n = 0, -1,1, -2,2,-3,3, etc.
In particular, sin(pi/2) = 1 ( n = 0) and sin(-3pi/2) -1 ( n = -1) and those argument values lie in the interval [-2pi, 2pi]

Answer:
60°
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the 2 interior opposite angles.
let the other interior angle be x, the
x + 50 = 110 ( subtract 50 from both sides )
x = 60
Thus the other interior opposite angle is 60°
7.50 x 8 = 60
9.25 x 9 = 83.25
83.25 + 60 = 143.25
143.25 - 20.68 = 122.57
Part A : 122.57
122.57/4 = 30.64
122.57-30.64 = 91.93
Part B : 91.93
