Amanda [17]

Answer:

17.7 cm

Step-by-step explanation:

One of the legs of a right triangle measures 12 cm and the other leg measures 13 cm find the measure of the hypotenuse if necessary round the nearest 10th

To find the Hypotenuse of a right angle triangle, we solve using Pythagoras Theorem

Hypotenuse ² = Opposite ² + Adjacent ²

Hypotenuse = √Opposite ² + Adjacent ²

Opposite = 12 cm

Adjacent = 13 cm

Hence,

Hypotenuse = √12² + 13²

= √144 + 169

= 17.691806013 cm

Approximately = 17.7 cm

Therefore, the measure of the Hypotenuse is 17.7 cm

Answer:

Thomas has 45

Emma 30+45=75 pound

Step-by-step explanation:

Ratio is 3/5

Tomas receives x money

Emma receives x+30

3/5=x/30+x

3(30+x)=5x

90+3x=5x

90=5x-3x

90=2x

x=90/2=45

Thomas has 45

Emma 30+45=75 pound

45/75=3/5
