Explain why all triangles have at least two acute angles.

If two angle measures of a triangle were each greater than or equal to

Answers

Answer:

Step-by-step explanation:

4x + 6 = 102

-6. -6

4x= 96

x=24

Sum of all angles of triangle=180°

So, 102 + 4x + 6 + x = 180

or 5x + 108 = 180

or 5x = 180 - 108

or 5x = 72

or x = 72/5

or x = 14.5

So, x = 14.5°
