The answer is 75 degrees I believe.
45 + 60 + x = 180
I’m pretty sure I’m correct but I’m so sorry if I’m wrong.
Ratio of 30-60-90 triangles in terms of side lengths is 1-

-2
So, the side across the 30-degree angle is 6.25.
Thus, the side across the 90-degree angle (hypotenuse) is 12.5.
Multiply the one by the 2 and the three by the 2. Put the decimal back in and add the negative sign
Point-slope form:
y - y₁ = m(x - x₁) "m" is the slope
Since you know:
m = -2/5
(x₁ , y₁) = (-3, -5)
Plug it into the equation:
y - y₁ = m(x - x₁)
y - (-5) = -2/5(x - (-3))
y + 5 = -2/5(x + 3)
