Answer:
≈ 44.0°Step-by-step explanation:
Use trigonometry
The ratio of the adjacent side of a right triangle to the hypotenuse is called the cosine:
cos x = 18/25 = 0.72cos x = 0.72x = arccos 0.72x = 43.9455° ≈ 44.0° roundedRelated Questions

Which inequality is shown in this graph? (0, 2) (-1,-2)
A. y2-4x+ 2
B. yz 4x + 2
C. ys - 4x + 2
D. y = 4x+2
Answers
Answer:
D) y = 4x + 2
Step-by-step explanation:
Explanation:-
Given ( 0, 2) ( -1 , -2 )
Given in equalities y = 4x + 2
put point (0,2) in equation y = 4x +2
2 = 4(0) +2
2 = 2
Therefore satisfies the point (0,2) equation y = 4x +2
put point (-1,-2) in equation y = 4x +2
-2 = 4(-1)+2
-2 = -2
Therefore satisfies the point (-1,-2) equation y = 4x +2

Solve the following equations
7(3x + 5) - x = 75
Answers
Answer:
x = 2
Step-by-step explanation:
7(3x + 5) - x = 75
1. Distributive property
multiply 7 by whatever is in the parenthesis
7*3x + 7*5 - x = 75
21x + 35 - x = 75
2. Combine like terms
21x - x = 20x
20x + 35 = 75
3. Subtract 35 on both sides
20x + 35 - 35 = 75 - 35
20x = 40
4. Divide both sides by 20 since u want to isolate the variable
20x/20 = 40/20
x = 2
And thats ur answer
Hope this helped!

Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
Sin 30 = 10 / x ______(10
We know that,
Sin 30 = 1/2 _____(2)
So,
Substituting (2) in (1).
1/2 = 10/x
x = 10 x 2
