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 )

Question 2 is 2/7
Question 3 is 1/3
2 a + b = 15.7
Since the sides are equal length, the equation is:
2 · 6.3 + b = 15.7
We can solve it:
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1 cm
Answer:
(-1/2, 27/2)
Step-by-step explanation:
Midpoint formula: (x^1 +x^2/ 2, y^1 +y^2/ 2)
(-4 +3 /2, 12+15/ 2) -> (-1/2, 27/2)
