A triangle has sides with lengths of 45 feet, 76 feet, and 90 feet. Is it a right triangle?
Yes or No

NO

Step-by-step explanation:

Longest side of the triangle has the length = 90 feet

Other two sides are 45 feet and 76 feet

If the triangle is a right triangle then square of the longest side is equal to the sum of squares of the other two sides.

=>

Left Hand Side = = 8100

Right Hand Side =

= 2025 + 5776

= 7801

So the left hand side is not equal to right hand side. The condition for right triangle is NOT satisfied.

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !
