Hello!
Angles in a triangle sum up to 180°, so:
180° = 58° + 58° + m∠3
Combine and subtract:
180° = 116° + m∠3
64° = m∠3
Thus, the answer is D.
total area = 3×7 + 3×10 + 12×5
= 21+ 30 + 60 = 111
With the store`s existing 25% off sale, the price is 75% of the base price. With a 25% off coupon:
0.75 * 0.75 = 0.5625
The new price is 56.25% of the base price. And because a shopper had enough money to cover just 50% of the base price, he was disappointed.
Answer:
The answer is x=60.
Since the arch and its base are symmetrical, so that other side of arch should be at (x, 20). Refer to x-axis when y is equal to 20. Thus, x=60.
I just took the test and the answer is correct.
