Choose the statement that best describes the value of 174

Answers

The answer of this question is b

Answer:

A. The value is between 13.0 and 13.5

Step-by-step explanation:

You can use perfect squares around this to guestimate the range

13x13= 169

14x14= 196

Because it is way closer to 169 and lesser than the halfway point, you can conclude it is in the 13 to 13.5 range rather than the 13.5 to 14 range

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

The thing is Similar Triangles

Answers

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.
