Mhanifa or anyone please answer!! Find x

Step-by-step explanation:

To solve this problem, use the trigonometric ratios. The trigonometric ratios for a right triangle (a triangle with a right angle are the following).

In this case, one is given the hypotenuse (the side opposite the right angle) and one is asked to find the side adjacent to the given angle. Therefore, it would make the most sense to use the trigonometric ratio of cosine ().

Substitute,

Inverse operations,

Simplify,

false

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
