X^2 - x - 90 =0
This equation is in standard form ax^2+ bx + c
The sum of the solutions is -b/a (a and b are the coefficients from the equation above, not the solutions to the equation)
The answer is 1/1 = 1
The angle of elevation for the given figure will be 68.198°.
<h3>What is a trigonometric function?</h3>
The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.
The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.
The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.
Given the figure is making a right-angle triangle with a base of 10m and a height of 45 - 20 = 25 m
By trigonometric function tan
Tanθ = 25/10
θ = 68.198°
Hence "The angle of elevation for the given figure will be 68.198°".

Answer:
Step-by-step explanation:
A. Right Triangle
Use a system of equations to solve this problem. Let "x" represent the number of classic cars, and "c" represent the number of cars.
320 = x + c
x = 4c
In this case, it'll be easiest to use the substitution method to solve the system of equations.
320 = (4c) + c
320 = 5c
Now solve for "c":
320/5 = c
c = 64
Since you now know there are 64 regular cars, you can subtract that from the total amount for the number of classic cars.
320 - 64 = 256
There are 256 classic cars.
To check the answer, multiply 64 by 4 and make sure it equals 256.
64 x 4 = 256
