y = ? degrees Round to the nearest tenth
The opposite side is 8 cm
the adjacent side is 10 cm
its a right triangle
y is the angle above the right angle
PLEASE HELP!
I assume that you are using the words "adjacent" and "opposite" in relation to angle y
then tany= opposite/adjacent = 8/10
tany = .8
angle y = appr 38.7°
To find the measure of angle y in the right triangle, you can use the trigonometric function tangent (tan).
The tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side. In this case, the opposite side is 8 cm and the adjacent side is 10 cm.
So, the equation for tangent is tan(y) = opposite/adjacent = 8/10 = 0.8.
Now, to determine the value of angle y, you need to find the inverse tangent (also known as arctan or tan^-1) of 0.8.
Using a scientific calculator or an online calculator, find the inverse tangent of 0.8. The result is approximately 38.7 degrees.
Therefore, the measure of angle y is approximately 38.7 degrees when rounded to the nearest tenth.
