Solving a quadratic equation we will find that Angle 1 measures 29°.

How to find the angle?

We know that opposite angles have the same measure, then we will have that:

(3y^2 + 2y - 10)° = (2y^2 + 7y + 4)°

Solving that we get:

y^2 - 5y - 14 = 0

y = (5 ±√(5^2 - 4*(-14))/2

y = (5 ± 9)/2

Then the positive solution is:

y = (5 + 9)/2 = 7

Then the measure of the left angle is:

2*7^2 + 7*7  +4 = 151°

Angle 1 is supplementary of that angle, then it measures 29°.
