The two shorter sides of an obtuse triangle measure 15 inches and 3 feet. describe the length of the longest side. explain your reasoning.

18

Step-by-step explanation:

The longest side of the triangle is known as the hypotenuse. To find the hypotenuse, you would use the equation a^2+b^2=c^2.

The a and b represent one side of the triangle so it wouldn’t matter which side you use for them. The c represents the hypotenuse.

When you plug in the side lengths, the equation would be:

10^2+15^2=c^2

100+225=c^2

325=c^2

Now you find the square root of 325 which is approximately 18,

And so the final answer is 18.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
