Answer:
Quadratic
Step-by-step explanation:
A linear equation is just a line and an exponential function goes in the same direction
A quadratic us a parabola which has a turning point
X(a+b)-y(a+b)
*factor out (a+b)*
=(a+b)(x-y)

Here are the basic rules for a right triangle:
One angle is always 90° or right angle.
The side opposite angle 90° is the hypotenuse.
The hypotenuse is always the longest side.
The sum of the other two interior angles is equal to 90°.
The other two sides adjacent to the right angle are called base and perpendicular.
a quick way to find angle 1, is just to look at the figure. there seems to be bisecting angles, so angle FCE and angle 1 are congruent. (meaning angle 1 is also 34 degrees)
hope this helps! lmk.
