Answer:
<u>The missing side is 12 cm length</u>
Step-by-step explanation:
1. Let's review the information given to us to solve the case correctly:
Length of the longest side= 13 cm
Length of one leg = 5 cm
2. Using the Pythagorean theorem for finding the length of the second leg, because this is a right triangle:
2nd leg² = Length of the longest side ² - Length of one leg²
2nd leg² = 13 ² - 5 ²
2nd leg² = 169 -25
2nd leg² = 144
2nd leg = √144
2nd leg = 12 cm
<u>The missing side is 12 cm length</u>
Answer:
Martina is 53 inches tall.
Step-by-step explanation:
In order to write an expression that relates the siblings heights we need to attribute variables to each brother. First we will call Martina's height as "m", then we can call her little brother's height as "b". The problem states that Martina's height is 3 inches less than twice the height of her brother so we have:
m = 2*b - 3
Then the problem gives us the height of her brother that is 28 inches tall, so b = 28. We can now compute Martina's height:
m = 2*28 - 3 = 56 - 3 = 53 inches.
-5.55 - 8.55c + 4.35c
-8.55c + 4.35c = -4.2c
-5.55 - 4.2c is the answer.
