By the external angle theorem

5x = (5x - 30) + m < RST

m < RST = 5x - 5x + 30 = 30

also m < STR = m < SRT = 5x - 30

So as there are 180 degrees in a triangle:-

5x - 30 + 5x - 30 + 30 = 180

10x = 180 +30+30-30 = 210

x = 21 answer

TRI has vertices T(-3, 4), R(3, 4), and I(0,0). Is TRI scalene, isosceles, or equilateral?

KatRina [158]

Answer:

Isosceles

Step-by-step explanation:

Graph your triangle!

Then, do the distance formula. So from T to I is 5 units, R to I is 5 units, and T to R is 6 units. As two side lengths are congruent, the triangle is isosceles.

Hope this helps!
