Find the missing side of the triangle
(Pythagorean theorem)

18.8 in

Step-by-step explanation:

the pythagorean theorem states that for a right triangle with legs a and b and hypotenuse c,

the two legs are 8 and 17 inches. so we have . simplify to get sqrt(353) or around 18.79in

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
