Triangle qrs is a right triangle. complete the similarity statement. δstr ~ δ

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

a. the measures of two angles have a sum of 180º if and only if the angles are supplements.

the angles are supplementary so they can only equal 180

so 75 people in the room, 3 more enter so

75 + 3 = 78 so then 2 leave so

75 + 3 = 78 - 2 = 76

then since im not sure what beat up means but im guessing they stayed because it doesnt sya they left so

hope i have a great day!
