Answer:

x-intercept = -6

<h2>y-intercept = -21</h2>

Step-by-step explanation:

x - intercept is for y = 0

y - intercept is for x = 0.

We have y = -2x - 21.

Substitute:

x = 0 → y = -2(0) - 12 = 0 - 12 = -12

y = 0 → 0 = -2x - 12 <em>add 2x to both sides</em>

2x = -12 <em>divide both sides by 2</em>

x = -6

Answer:

the length of the opposite side (x), is 27.2

Step-by-step explanation:

For the given right triangle problem;

the opposite side of the given angle, opp. = 22

the hypothenuse side, hypo. = x

given angle of the triangle, θ = 54⁰

The length of the opposite side (x), is calculated as follows;

$sin \ \theta = \frac{opp.}{hypo.} \\\\sin (54) = \frac{22}{x} \\\\x = \frac{22}{sin(54)} \\\\x = 27.2$

Therefore, the length of the opposite side (x), is 27.2
