Mrs. Rayo cut one piece of pie as shown in the drawing. From the first cut to the second cut, she rotated the knife
60 one-degreee turns.
second cut
o
first cut
What is the measure of the angle formed by the piece of
pie?
40°
60°
100°
O 180°

60°

Step-by-step explanation:

She rotated the knife 60° so the second cut will make an angle of 60° to the first cut.

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
