Answer:
the internal angle sum of a Triangle is
<u>Option B) </u><u> </u><u>180°</u>
180
Step-by-step explanation:
sorry if this is wrong, if it isn't...brainliest pleasee :>>>
just kidding, lol.
A.200
x 2 + 5 x + 6
y = m x + c
y- intercept
x = 0
y = (-2) (0) + 3
=3
(x =0, y = 3)
there is an 86% change
x=5
since two sides are congruent, the two unknown angles are congruent.
All triangle angles total 180 degrees.
so:
180-88=92
92/2=46
9x+1=46
9x=45
