Answer:
C. 139 ft
Step-by-step explanation:
Height of the pole = x + 4 ft
First, find x using trigonometric function.
Reference angle = 44°
Opposite side length = x
Adjacent side length = 140 ft
Apply TOA, which is:
Tan 44 = opp/adj
Tan 44 = x/140
Multiply both sides by 140
140 × Tan 44 = x
135.196428 = x
x ≈ 135 ft
✔️Height of the pole = x + 4 ft = 135 + 4 = 139 ft
Answer:
a=2
Step-by-step explanation:
Subtract 12 from both sides
8a+12-12=-3a+34=12
simplify
8a=-3+22+3a
Add 3 to both sides
8a+3a=-3a+22+3a
simplify
11a=22
divided both sides by 11
11a/11=22/11
simplify
a=2
I believe the answer is C
Answer:
5, 5, 7, 5, 5, 7, 5
Step-by-step explanation:
So investment is $140 and interest is 3% per yea
yo convert % to number 3/100 = .03
so for one year. $140 x .03 = $4.20/year
in two years you have $4.20+$4.20 =$ 8.40!
Answer is $8.40 or 2 years
