In Triangle
ABC with the right angle at C, let a,b, and c be the opposite, the adjacent, and the hypotenuse of ∠A. Then, we have
sin A=ac⇒m∠A=sin−1(ac)
sin B=bc⇒m∠B=sin−1(bc)
I know its not the answer but I hope it was helpful
Answer:
130
Step-by-step explanation:
The two angles with measurements are vertical angles and vertical angles are equal
12x-2 = 10x+20
Subtract 10x from each side
12x-10x -2 =10x-10x+20
2x-2 = 20
Add 2 to each side
2x-2+2 =20+2
2x= 22
Divide each side by 2
2x/2 =22/2
x =11
We want to find 2x-2
12(11)-2
132-2
130
It would also be 25 degrees
