Find the area of a 45°-45°-90° triangle with a hypotenuse of 24. a. 144 square units c. 99 square units b. 125 square units d. 100 square units
Answers
Answer 1
Answer:
area=1/2 times base times height
remember that 45-45-90 triangle has sides of x,x and x√2
(legs are measure x and hypotonuse=x√2)
the legs are equal and are also the base and height
find the legs (x=leg)
hypotonuse=24
24=x√2
divide both sides by √2
24/(√2)=leg=base=height
volume=1/2 times base times heigth
V=1/2 times (24/√2) times (24/√2)
V=1/2 times (576/2)
V=576/4
V=144 units^2

SA=2(LW+LH+WH)
SA=94
L=3
W=4
94=2(3*4+3H+4H)
divide both sides by 2
47=3*4+3H+4H
47=12+7H
minus 12 both sides
35=7H
divide oth sides by 7
5=H
