Answer:
x = -3
Step-by-step explanation:
Notice that the addition of angle <CDH plus angle <HDE have to give the measure of angle <CDE (which is 144 degrees as stated in the problem)
Then, we can say in equation form:
<CDH + <HDE = 144
replacing with their expressions in terms of x:
x + 93 + 57 + x = 144
solving for x:
2 x + 150 = 144
2 x = 144 - 150
2 x = - 6
x = -3
X=3
91 + x^2
91 + 3^2
91 + 9
91 + 9 = 100
Answer:
8
Step-by-step explanation:
If 8x = 4, then you can solve for x by dividing both sides by 8. Therefore, x = 4/8 or 1/2.
Then to solve 2 + 12x you simply plug in 1/2 for x.
2 + 12x
2 + 12(1/2)
2 + 6
8
