Answer:
B
Step-by-step explanation:
Theta is found using the sin-1 function. Start off with the sin of theta.
sin(theta) = opposite over hypotenuse.
sin(theta) = 3/8 = 0.375
Theta = Sin-1 (0.375)
Theta = 22.02 degrees.
Answer: B
The sum of angle AOB and angle BOC is equal tot he angle of AOC so
6x+5 +4x-2 = 8x+21
10x+3=8x+21
Subtract three and 8x from both sides
2x=18
Divide by two
x=9

Answer:
- C
- Not clear
- A
- A
- C
Step-by-step explanation:
1) 2x + 246 = 360° (Vertically opposite and angle at a point)
2x = 360 - 246
2x = 114°
x = 114 / 2
x = 57°
3) Since <ABD is a right angle (i.e its sum is 90°)
<CBD = 90° - 75° = 15°
5) <1 = <2 (Vertically opposite angles are equal)
12x + 3 = 10x + 15
12x - 10x = 15 - 3
2x = 12
x = 6
Therefore,
<2 = 10(6) + 15
<2 = 75°
