Answer:
a
Step-by-step explanation:
it's a right triangle so we can use the pythagorean theorem to find h
pythagorean theorem: a^2+b^2=c^2
h^2+19^2=21^2
h^2+361=441
h^2=80
h≈ 8.9ft
Answer:
0.1
Step-by-step explanation:
There are ten tiles and one G and 0.1 is a tenth of one, so your chances are 1 in 10
First, find the area of the entire traingle using the formula bh/2.
18*9/2=81 cm^2
Then subtract the area of the smaller triangle within the larger one (white triangle). It has the same base but a height of only 4.
18*4/2=36 cm^2
81-36=45
Final answer: 45 cm^2
G-8=B you can't find out B (boys) until you know how many G (girls) there are in Mrs. Davis's class
