# What is the temporary assumption to prove that A is an obtuse angle by proof of contradiction?

- A is the right triangle
- A is an acute angle
- A is not right or acute angle
- A is not an obtuse angle

### If G is the centroid of triangle ABC,

Find BE.

BG = 4x + 4

BG = 2/3 BE

4x + 4 = 2/3 (7x + 5)

12x + 12 = 14x + 10

2x = 2

x = 1

BE = 7x + 5

= 12
