What is the length of the hypotenuse of the triangle?<br> 7 ft<br> 4 ft
stepladder [879]

Answer:

√65 ft = 8.1 ft

Step-by-step explanation:

We solve using Pythagoras Theorem

c² = a² + b²

c = √a² + b²

Where c = Length of the Hypotenuse

a = 4ft , b = 7ft

Hence

c = √4² + 7²

c = √16 + 49

c = √(65)

c = 8.0622577483 ft

Approximately = 8.1 ft

Therefore, the length of the hypotenuse is √65 ft = 8.1 ft

if two angles of a triangle have measures of 42 degrees and 20 degrees what is the measure of the third
Mila [183]
Every triangle has an angle measure of 180 degrees.

Combine like terms.

62+x=180

Subtract 62 from both sides

x=118.
