Hey there! :)
Answer:
x = 12.
Step-by-step explanation:
Given:
Cross multiply to solve for x:
3 · 20 = 5 · x
60 = 5x
Divide by 5:
12 = x.
Answer:
B. Vertical angles
Step-by-step explanation:
The measure of the hypotenuse side is 21.66 units.
In the given figure, the measure of hypotenuse is x, the measure of angle is 37° and the measure of leg is 17.3 units.
<h3>What are trigonometric angles?</h3>
Trigonometric angles are the angles in a right-angled triangle using which different trigonometric functions can be represented. Some standard angles used in trigonometry are 0º, 30º, 45º, 60º, 90º.
Now, cos θ=(Base/Hypotenuse)
cos 37°=17.3/x
⇒ 0.7986=17.3/x
⇒ 0.7986x=17.3
⇒ x=17.3/0.7986
⇒ x=21.66 units
Therefore, the measure of the hypotenuse side is 21.66 units.

Rise=16, run=7. Slope is rise/run, and therefore is 16/7. The run is considered to be the x coordinate. Since the x coordinate on the point is 21, we know it has moved 3 exact points away from the origin (21/7=3). We can use this movement of 3 exact points to determine the y coordinate as well. Since the rise (y) is 16 for every exact point on a graph, we know the graph has risen 48 units (16x3=48). So, the point ends up being (21,48). The rate of change is 16cm per 7 minutes, or 2.28cm/minute. The equation is Y=(16/7)X (no y intercept because the graph starts at the origin). The equation gives you the y value of 48 when x is equal to 21.
