Answer:
x=2,x=7
Step-by-step explanation:
-3x^2+27x=42
x^2-9x+14=0
x^2-2x-7x+14=0
x*(xi2)-7(x-2)=0
(x-2)*(x-7)=0
x-2=0
x-7=0
x=2
x=7
Tan52° = x/29
The angle of elevation is 52°, so that must be inside the tan function.
Tan is the ratio of the opposite side to the adjacent side. Jessica’s height is unknown, so we can call that x. The adjacent side of the triangle is the shadow, which is 29’m. Since tan is opposite over adjacent (remember SOH CAH TOA), the fraction must be x/29.

Answer:
Step-by-step explanation:
Solve for the value of 
:
-Take 
and subtract it from 
:
-Subtract both sides and convert 
to a fraction:
Since both 
and 
have the same denominator, then you would subtract the numerator:
-Multiply both sides by 
, which is the reciprocal of 
:
-Divide 
by 
:
So, therefore, the value of is 
.
