Answer:
The answer is D) 60
Step-by-step explanation:
If I did this correctly it simplifies to 0 = 8. So I think B is the correct answer. Hope this helps!!
-6x-x^2-8 = -(x+2) x (x+4)
(This is if you are factoring the expression)
Hey there! :)
Answer:
m∠A = 72°.
m<B = 108°.
Step-by-step explanation:
In a parallelogram, the opposite angles are congruent.
Therefore, we can set the two expressions equal to each other:
5y - 3 = 3y + 27
Add 3 to both sides:
5y = 3y + 30
Subtract 3y from both sides:
2y = 30
Divide both sides by 2:
y = 15
Substitute this value of y into an expression to solve for the measure of ∠A:
5(15) - 3 = 72°. m∠A = 72°.
In parallelograms, the neighboring angles are supplementary. Therefore:
m∠A + m∠B = 180°
72° + m∠B = 180°
m<B = 108°.
