Check the picture below.
you have 3 medians segments up there.
Y^2 + 18y + 81 = 0
(y + 9)^2 = 0
y + 9 = 0
y = -9
Answer:
31, 114 and 35
Step-by-step explanation:
I set up the equation as such:
(3x + 21) + (x + 4) + x = 180
then I combined like terms:
5x + 25 = 180
And then solving for x I get:
5x = 155
x = 31
And then plugged the solved x value into the terms to give:
(3(31) + 21) = 114
(31 + 4) = 35
alongside the found angle of 31.
