The perimeter of GHJ
Dafna1 [17]
They have a scale factor of 5:6 so first we need to find the perimeter of KLM:
11 + 14 + 17 = 42
Then apply the scale factor of 5:6:
\frac{5}{6}  =  \frac{x}{42}
Set the denominators equal:
\frac{35}{42}  =  \frac{x}{42}
So we see that the perimeter of GHJ is 35.

Find the missing side.​
Vitek1552 [10]

Answer:

5

Step-by-step explanation:

This is a right triangle, but note that you only know the measurement of one angle, which is 90 degrees.

Use the following formula to solve:

a² + b² = c²

In which:

a & b = shorter sides

c = hypotenuse

Plug in the corresponding numbers to the corresponding variables:

(3)² + (4)² = ?²

Solve. Remember to follow PEMDAS. First, solve the exponents, then add:

(3)² = (3 * 3) = (9)

(4)² = (4 * 4) = (16)

9 + 16 = ?²

25 = ?²

Isolate "?". Root both sides:

√(25) = √(?²)

? = √25 = √(5 * 5) = 5

Your missing side's measurement is 5.
