Answer:
a = 5
b = 12
c = 13
Step-by-step explanation:
a^2+b^2=c^2
b-a=7(b=a+7)
c=a+8
Then, substitute
a^2+((a+7)*(a+7))=c^2
a^2+a^2+7a+7a+49=c^2
2a^2+14a+49=c^2
Because c = a+8
2a^2+14a+49=(a+8)(a+8)
2a^2+14a+49=a^2+16a+64
a^2-2a=15
a^2-2a-15=0
(a-5)(a+3)=0
a = 5,-3
a = 5(a side cannot be negative)
Plug in a=5 to the other equations to get
a = 5, b = 12, c = 13

Answer:
1.2761445e+16
Step-by-step explanation:
8*48=384/7"16=1.2761445e+16
To simplify this problem you need to combine like-terms.
-2b + 3b = b
-6 + (-2) = -8
So your simplified answer would be -
b + (-8)

Answer:
49.3 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan48° = 
= 
( multiply both sides by 30 )
30 × tan48° = x , then
x ≈ 33.3
Height of tower = 33.3 + 16 = 49.3 ft ( to the nearest tenth )
