Answer:
19.72 ft
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between angles and sides of a right triangle:
Tan = Opposite/Adjacent
Then the relations in the attached drawing are ...
tan(α) = 42/73
tan(α +10.3°) = (42 +SH)/73
Solving the first equation for α, we get ...
α = arctan(42/73)
Solving the second equation for SH, we get ...
73 tan(α +10.3°) = 42 +SH
SH = 73·tan(arctan(42/73) +10.3°) -42 = 73·tan(29.91°+10.3°) -42
SH = 73·0.84547 -42 = 19.720 . . . . feet
The height of the statue is about 19.72 feet.

Answer: 5 + 25n
Explanation: Let's simplify this problem using the distributive property.
In this problem, the 5 "distributes" through the parentheses which means that it multiplies by each of the terms inside.
So we have 5(1) + 5(5n) which simplifies to 5 + 25n.
Answer:
57
Step-by-step explanation:
because all the angle of a triangle add up to 180
180-63-60=57
46.6 billion
explanation:
Isolate S on the left side by adding 1.9x to both sides. this gives you S = 4.8 + 1.9x. Plug in 22 for x because 2020 is 22 years from 1998.
4.8 + 1.9(22) = 46.6
