Question

I need some help figuring out these questions. I will give medals

Answer 1

6. Which three lengths could be the lengths of the sides of a triangle?
a. 6cm, 23cm, 11cm
b. 10cm, 15cm, 24cm **My answer
c. 22cm, 6cm, 6cm
d. 15cm, 9cm, 24 cm


9. The lengths of the sides of a triangle are 12, 13, and n. Which of the following must be true?
a. n is bigger than or equal to 1
b. n<13
c. 1<n<13
d. 1<n<25** My answer

10. If AB=BC in triangle ABC then which of the following must be true?
a. angle A< angle C
b. angle A=angle C** my answer
c. angle A> angle C
d. angle A> angle B

Answer 2

10 will be b

Answer 3

if say b= 4
in order to get the same answer on both a and c need to be the same
4(2)= 8 and 4(2) =8 otherwise it would look like
4(2) =8 and 4(3) = 12

Answer 4

Okay. Thanks! Do you think you can help me one more question?

Answer 5

i can

Answer 6

Thanks. In triangle ACE, G is the centroid and BE=9. Find BG and GE.

Answer 7

Where is B located? I will need to assume that B is located at the midpoint of side AC, in order to solve the problem.

Under this assumption, BE is a median. Along any median, the centroid of a triangle is always located 2/3 of the way from the vertex to the midpoint of the opposite side, so the centroid G is 2/3 of the way from E to B.
So we have GE = (2/3)BE.

Furthermore, by segment addition, BG + GE = BE.

Since BE = 9, GE = (2/3)(9) = 6.
Then BG + 6 = 9, which gives BG = 3.
