The sum of the measure of angle M and angle L is 116
the measure of angle m is 50
the measure of angle L is 7x-4
what is the value of x?
a.10
b.12
c.15
d.20
If the sum of the measure of angle M and angle L is 116, we can write the equation as follows:
M + L = 116.
Given that the measure of angle M is 50, we can substitute this value into the equation:
50 + L = 116.
We are also given that the measure of angle L is 7x - 4. Substituting this value into the equation, we get:
50 + (7x - 4) = 116.
Simplifying this equation, we have:
7x + 46 = 116.
Subtracting 46 from both sides of the equation, we get:
7x = 70.
Dividing both sides of the equation by 7, we find:
x = 10.
Therefore, the value of x is 10, so the answer is a. 10.
