X=-3
because
-4x=21-9
-4x= 12 divide both sides
x=-3
The square root of 10 because
sqrt(10) ^2 * 3.14 =
10*3.14 = 31.4
Given the triangles ABC and PQR.
Angle A = Angle P
Angle B = Angle Q
Angle C = Angle R
Angle B = 3v+4
Angle Q = 8v-6
Let's find v
3v+4 = 8v-6
-5v = -10
v = 2
Angle B = 3v + 4
Angle B = 3(2) + 4
Angle B = 10.
The correct answer is letter C. 10
The answer is 20
Hope this helps!
