Step-by-step explanation:
The height is given by the following function:
Will the superhero make it over the building?
We have to find if there is values of x for which f(x) = 612.
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
If 
, the polynomial has no solutions.
In this question:
We have to find 
We have that 
. So

Answer:
<h3>
m∠BAC = 80° </h3>
Step-by-step explanation:
m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°
65° + 35° + m∠BAC = 180°
m∠BAC = 180° - 100°
m∠BAC = 80°
The number is 17 61/100. 61/100 can't be reduced, because 61 is a prime number.
