Answer:
Opposite sides are corresponding (AB = DC).
Opposite angles are corresponding (D = B).
Consecutive angles are supplementary (A + D = 180°).
If one angle is right, then all angles are right.
The diagonals of a parallelogram hemisect each other.
Step-by-step explanation:
Apply lg on both sides.
lg7^x^2 = lg9^x
Bring the power forward.
x^2lg7 = xlg9
x^2/x = lg9/lg7
x = lg9/lg7 = 1.13
Answer:
x=80 degrees
Step-by-step explanation:
Answer:
i think you have to multiply the sides..
Step-by-step explanation:
60*5%=60*5/100=300/100=3
So the answer is 3
