Find the measure of x. (to the nearest tenth)
1 answer:
For the given triangle, x measures A) 25.7 units.
Step-by-step explanation:
Step 1:
In the given triangle, the angle is 56°. The adjacent side has a length of x units and the hypotenuse of the triangle measures 46 units.
To calculate the value of x, we determine the cos of the triangle where we divide the length of the adjacent side by the length of the hypotenuse.
Step 2:
The length of the adjacent side = x units.
The length of the hypotenuse = 46 units.
The angle of the triangle = 56°.
So x = 25.7186 units, rounding this is off we get option A.

Step-by-step explanation:
Given: when Zane was 20 meters below the edge of a volcano. He heard some rumbling, so he decided to climb up out of there as quickly as he could. He managed to climb up 4 meters each second and get out of the volcano safely.
We have to graph Zane's elevation relative to the edge of the volcano (in meters) as a function of time (in seconds).
Let he takes x seconds to get out of the volcano.
and y be the distance covered by the volcano to reach Zane.
Then, to reach the edge of volcano,
Thus, The equation that represent Zane's elevation relative to the edge of the volcano (in meters) as a function of time (in seconds). is given by
f(x) = -4x + 20
At x = 0 the Zane will be at f(0) = 20 that is 20 meter below the volcano.
Thus points are (0,20)
and when x = 5 Zane will be escaped from volcano.
Thus points are (5,0)
Plot this and obtained the graph for the given equation as attached below.
