Find the value of x in the parallelogram.

Mathematics
1 answer:
wlad13 [49]3 years ago
5 0

Answer:

Since it's a parallelogram, the length of AD and BC are the same.

Hence, x + 21 = 12x - 1.

x + 21 = 12x - 1

12x - x = 21 + 1

11x = 22

x = 2

Therefore, x = 2.

In two days it will be 50% so, .50(932.4miles)=466.2 miles is the answer.

What is the area of a triangle that has a base of 15 1/4 in and a height of 18 in?
Aleonysh [2.5K]
The area of a triangle = 1/2 base * height (basically half of a rectangle)

so 1/2 * 18 * 15.25 = 9*15.25 = 137.25

don't forget units so the answer is 137.25 inches squared
