The answer is 2x-y

step-by-step explanation
in order to simplify you have to come one like terms and in this case you have your 3x and you’re subtracting x which is also know as 1x.
3x - 1x = 2x (then you still have your y) so 2x-y

Use the diagram to answer the question. What is the measure of ∠A? Enter the correct value. Do not enter the degree symbol.

forsale [732]

Answer:

Measure of ∠A = 60.07°

Step-by-step explanation:

From the figure attached,

ΔABC is a right triangle,

Measure of side AC = 15 units

and measure of side BC = 13 units

By applying Sine rule in this triangle,

SinA = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

Opposite side of angle A = Side AC

and hypotenuse of the triangle = Side BC

SinA = $\frac{13}{15}$

A = $\text{Sin}^{-1}(\frac{13}{15})$

A = 60.07°

Therefore, measure of angle A is 60.07°.
