HELP?!?!?!?!?!?!?!? please?!?!?!?!
1 answer:
Answer:
8
Step-by-step explanation:
Hello There!
This is an example of a 30 - 60 - 90 triangle
We are given the long leg and we need to find the hypotenuse
First we want to find the shorter leg
To do so we just take away the from the 4
so the shorter leg is equal to 4
Now to find the hypotenuse
Well according to the 30-60-90 triangle rule
the hypotenuse is equal to twice the size of the short leg
4*2=8
hence, the answer is option 2

Step-by-step explanation:
Given:
Answer:
a. height = 12
b. area = 228
Step-by-step explanation:
a. To find the height, we can use the triangle formed by the side that measures 15, the side that measures 9. and the height. The hypotenuse of the triangle(the longest side opposite of the right angle), is 15. We can then use the Pythagorean Theorem, which states that , where c is the hypotenuse, and a and b are the two other sides. In this case, we need to find a leg of the triangle, not the hypotenuse. What do we do? We can first call the height a, and rearrange the Theorem into
.
and
=12. Therefore, the height of the parallelogram is
b. To find the area of the parallelogram, we can use the area formula, which is Base*Height. The base is the flat side. We can find the base by adding 9+10=19, and
