These two triangles are similar .Find side lengths a and b .The two figures are not drawn to scale

Similar triangles may or may not be congruent.

The values of a and b are 6 and 22.5, respectively.

Because the triangles are similar, then the following equivalent ratios are true.

First, we calculate b using:

Express as fraction

Multiply both sides by 9

Next, we calculate a using:

Express as fractions

Multiply both sides by 15

Hence, the values of a and b are 6 and 22.5, respectively.

a = 6, b = 22.5

Step-by-step explanation:

One triangle is 2.5 times bigger than the other.

9*2.5=22.5 which means b = 22.5

15/2.5=6 which means a = 6

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
