<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,

Thus measure of angle y is 35.68 degrees
Take a look at the picture i sent you
<span>(x + 6y) − (3x − 10y)
= x + 6y -3x + 10y
= -2x + 16y
Value of A: -2</span>
Answer: x = 2, y = 9
Step-by-step explanation:
y = 9x - 9 Substitute x for 2
y = 9(2) - 9 Multiply 9 with 2
y = 18 - 9 Subtract 18 - 9
Final Answer: y = 9 and x = 2
