sin(
)=Sin(-0) =Sin 0=0
Option C Sin()=0
Also, using unit circle, Sin()=0
∠B + ∠B` = 180°
The Sine Law:
10 / sin B` = 9.2 / sin 60°
10 / sin B` = 9.2 / √3/2
sin B` = 0.94133
B` = sin^(-1) 0.94133
Answer:
C ) ∠B` = 109.73°, ∠B = 70.27°
They must equal 180°. Supplementary angles equal 180°
Answer:
x = 10
Step-by-step explanation:
If you add the angles up, you get 110, so the missing angle is 70. It is an isosceles triangle. The bottom length should be about 11.
Yes, it is, because, point-slope form is:
y - k = m (x - h)
I hope this helps!
