The measurement of one angle of a right triangle is 34 degrees. what is the measurement of the third angle.

The interior angles of a triangle add up to 180 degrees
so one angle is 34 degrees
another angle, if it is a right triangle, will equal 90 degrees
so lets label the third angle as x

34 + 90 + x = 180
124 + x = 180
x = 180 - 124
x = 56 <== ur 3rd angle

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
