Answer:
Step-by-step explanation:
For this problem i assume that the two lines that look parallel, are parallel
step 1
Find the value of x
we know that
----> by corresponding angles
solve for x
step 2
Find the value of y
we know that
---> by vertical angles
substitute the value of x
<em>Alternative method</em>
---> by vertical angles
---> by alternate exterior angles
Solve the system of equations
Answer:
-1/8
Step-by-step explanation:
The given expression is y⁻³
We want to find the value of the expression when y = -2
Thus;
At y = -2, we have; -2⁻³
According to law of exponents, x⁻⁴ = 1/x⁴
Thus; -2⁻³ = -1/2³ = -1/8
The solution to the problem is as follows:
<span>We use proportion :
Let the height of building = x ft.
We get x/21 = 15/6
x = 15*21 /6
x = 52.5 ft.
height of bldg = 52.5 ft
