Answer:</h2>
Since both angles are vertical angles, we need to set them equal to each other.

The final answer is <em>x = 10</em>.
Answer:
y=-5x+7
Step-by-step explanation:
Prallel lines have the same slope
so the slope of the unknown line is -5
and passes through(1,2)
y-2=-5(x-1)
slope-intercept form:y=-5x+7
Answer:
Step-by-step explanation:
4
Answer:one solution
Step-by-step explanation:
Given
a=42
b=34
angle A=117
using sine rule



sinB=0.7212

and A+B+C=180

Thus 2 triangles can be formed with given value
The answer is 200.
The reason is because if you have 50 teachers, and that is 1/4 of the number of total teachers, then you would multiply the number of basic math teachers by four.
