If X = 2 centimeters, Y = 6 centimeters, and Z = 6 centimeters, what is the area of the object?
Sedbober [7]

In order to answer the question, it's absolutely essential to have
enough of a description of the object to know which of its parts 
'X', 'Y', and 'Z' are, and what other parts it may have.

An ideal way to accomplish this would have been for you to include the
picture that accompanies the question, wherever you copied it from.

Find the measure of angle y. Round your answer to the nearest hundredth. Right triangle
e-lub [12.9K]
<h3>The measure of angle y is 35.68 degrees</h3>

<em><u>Solution:</u></em>

Given that,

hypotenuse 12

Opposite 7

Find the measure of angle y

y is unknown and is between the hypotenuse and adjacent side

The figure is attached below

In a right triangle, the sine of the angle is the ratio of the side opposite to the angle to the hypotenuse

Therefore,

sin\ y = \frac{opposite}{hypotenuse}\\\\sin\ y = \frac{7}{12}\\\\sin\ y = 0.5833\\\\y = sin^{-1}\ 0.5833\\\\Use\ arcsin\ calculator\\\\y = 35.6829 \\\\y \approx 35.68

Thus measure of angle y is 35.68 degrees
