Answer:

3a+5b

Step-by-step explanation:

3(a+b+)2b

<u>the first thing you'd do would be distribute 3 to a and b</u>

3a+3b+2b

<u>you then would combine like terms which are 3b and 2b</u>

3a+5b

3a+3b+2b=3a+5b

solve for a: a=-5b/3

solve for b: b=-3a/5

We are given that:

m∠AOB = m∠AOC + m∠COB

We are also given that:

m∠AOC = m∠COB + 15

m∠AOB = 155

Therefore:

155 = m∠COB + 15 + m∠COB

2 m∠COB = 140

m∠COB = 70°

and,

m∠AOC = m∠COB + 15 = 85°

 

Answers:

m∠COB = 70°

m∠AOC = 85<span>°</span>

The two triangles below are similar. What is the ratio of the corresponding side lengths? 4:9 4:2 26:26 4.5:2
MrRa [10]

Answer:

4 : 2

Step-by-step explanation:

We are given ΔABC ≅ ΔA'B'C'.

When two triangles are congruent, their corresponding sides and angles are congruent.

Since, the sides of the triangles are in relation,

AB = 2 × A'B' and side BC = 2 × B'C' i.e. 4 = 2 × 2 and 9 = 2 × 4.5.

Therefore, the ratio of the corresponding sides are given by 4 : 2 and 9 : 4.5 i.e. 2 : 1.

Since, the ratio of the corresponding sides comes out to be 2 : 1 = 4 : 2.

Hence, the ratio of the corresponding sides is 4 : 2.
