Answer:

<h2>X = 59°</h2>

Step-by-step explanation:

To find Angle X we use sine

sin∅ = opposite/ hypotenuse

From the question

WY is the opposite

WX is the hypotenuse

So we have

sin X = WY/ WX

sin X = 6/7

X = sin-¹ 6/7

X = 58.99

X = 59° to the nearest tenth

Hope this helps you

No, it would only work with similar terms. However, you would be able to multiply them, like 2x times 2y = 4xy.
