Answer:
choice f
Step-by-step explanation:
take ∆ abc
ab^2 = ac^2 + ab^2
400 = 225 + ab^2
ab =√ 175
∆aDB
bd = 20-x
ad^2 = 175 -(20-x)^2
∆acd
225 = x^2 + 175 - 400+ 40x - x^2
225 = -225 + 40x
450 = 40x
x = 45/4
Answer:
the actual answer is 78750
Step-by-step explanation:
summation of 2-176 in the equation 5n+5
Answer:
(8 − 10)² − 30 ÷ 5 × 6 + 2
=(-2)² -(6*6)+2=4-36+2=-30
I could be wrong here, but I think n is 4? I plugged it in, but I was a bit unsure of what you were asking. Wish you the best!
Answer:
Step-by-step explanation:
tan23=h1/500
h1=500tan23
tan50=h2/500
h2=500tan50
The height of the building is h1+h2 so
H=500(tan23+tan50)ft (exact)
H=808.1 ft (rounded to nearest tenth of a foot)
