Answer:
90ft2
Step-by-step explanation:
rectangle= BH
Triangle= BH/2
add em together and you get you're answer
(B is base and H is height)
The rule for quotients of similar bases with different exponents is:
(a^c)/(a^b)=a^(c-b) in this case:
15^18/(15^3)=15^15
To get the height to the nick we use the trigonometry formula:
tan θ=opposite/adjacent
θ=73°
opposite=h ft
adjacent=38 ft
plugging our values we get:
tan 73=h/38
thus
h=38 tan 73
h=124.29~124.3 ft
Answer: <span>C. 124.3 ft</span>
<span>56 is the answer because
8*7*6/3*2</span>
