Answer:
m∠x = 10°
Step-by-step explanation:
Since we are dealing with a <u>right triangle</u> and its two sides and one angle, we can use <u>trigonometry ratios</u>. Remember them all with the acronym SohCahToa.
"o" is for opposite side, "a" is for adjacent side, "h" is for hypotenuse side.
The ratios are:
sinθ = opposite/hypotenuse
cosθ = adjacent/hypotenuse
tanθ = opposite/adjacent
θ means the "angle of reference", or the angle you know or want to find. This determines which side is adjacent (touching) or opposite (not touching). The hypotenuse (longest side) does not change.
In this triangle, θ = x. The sides we know are hypotenuse and opposite. Therefore, we will use the sinθ ratio.
sinθ = opposite/hypotenuse
sinx = CB/AB Substitute the labels in the diagram
sinx = 4/23 Substitute known values (side lengths)
x = sin⁻¹(4/23) Isolate 'x'. Use calculator to solve.
x = 10.015....° Exact answer
x ≈ 10° Round to the nearest degree
Therefore the measure of angle x (m∠x) is 10°.
Answer:
Option c) 0.898
Step-by-step explanation:
Given :
Total variation = 20.711
Explained variation = 18.592
unexplained variation = 2.119
we know that coefficient of determination r² = 
= 
= 0.897687 ≈ 0.898
Option c, 0.898 is the answer.

Answer:
Donda
Step-by-step explanation:
Answer:
217 ft
Step-by-step explanation:
Sea level is 0 height.
217 ft below sea level is -217 ft.
The opposite of -217 ft is 217 ft.
|-217 ft| = 217 ft
