128 degrees.
An angle's supplement, when added to the original angle, will form a straight (180 degree) angle.
Step-by-step explanation:
A(x) = x² + 10x -75
= (x + 15)(x - 5)
Answer:
15.620
Step-by-step explanation:
use pythagorean theorm :)
(the 6 is pointless for this problem)
Answer:
x = 55
y = 70
Step-by-step explanation:
Since all three sides are equal, as indicated by the lines on the sides, all three angles are equal
Since a triangle is equal to 180 degrees
180/3 = 60
Each angle is 60 degrees
x+5 = 60
Subtract 5 from each side
x +5-5 = 60-5
x = 55
y-10= 60
y-10+10 = 60+10
y= 70
Ok but u forgot to add the picture
