Multiply both sides by 7. w=<span>105</span>

Since this is a 30-60-90 right triangle, we know that the sides exist in the proportion 1:3‾√

:2. The shortest side, 1, is opposite the 30 degree angle. Since side X is opposite the 60 degree angle, we know that it is equal to 1∗3‾√

Or about 1.73. Finally, side Y is opposite the right angle, and it is twice the shortest side, or 2.

3y^-4 × (2y^-4) = 6y^-8

= 6/1/y^8

= 6/y^8

.................................................

1) When x^1 multiply with x^2, 1 will add to 2 and become 3

= x^3

2) y^-1 = 1/y

3^-2 = 1/3^2 = 1/9

5^-2 = 1/5^2 = 1/25

**Answer:**

180°

**Step-by-step explanation:**

the 3 interior angles of a triangle add up to 180°
