Answer:
Already in standard form
Step-by-step explanation:
A quadratic equations standard form is ax^2 + bx + c. This equation is already in standard form.
ax^2 + bx + c
1/2 x^2 - 4x + 3
The angles of a triangle should add up to 180 degrees. in the left triangle, you should find the 3rd angle
75 + 50 + y = 180
125 + y = 180
y = 55
vertical angles are congruent, so the left angle on the right triangle will also be 55 degrees.
then you do the same thing to find x.
85 + 55 + x = 180
140 + x = 180
x = 40
