28 is the coefficient of x and 35 is the constant
Let the distance of Jill form the base of the tower be x, then tan 40 = 100/x
x = 100/tan 40 = 100/0.8391 = 119.18 meters
Let the height of the tower from the level of the top of Jill's apartment be y, then tan 30 = y/119.18
y = 119.18 x tan 30 = 68.8 meters
Therefore, the height of Jill's apartment is 100 - 68.8 = 31.2 meters
Answer:
D. 15
Step-by-step explanation:
Given the expression, 32 + 2n - 9, and a value of <em>n </em>= -4:
You can substitute the value of <em>n</em> into the given expression:
= 32 + 2n - 9
= 32 + 2(-4) - 9
= 32 - 8 - 9
= 15
Therefore, the correct answer is D. 15
