Answer:70
Step-by-step explanation:
step 1:add up the angles you know
step 2:subtract the answer (220) from the total angle measure of a square which is 360 then you get 140
step 3: divide 140 by 2 because the two angles on the sides are equivalent and you get 70
Y=-x^2+6x-8 is the y-intercept. so you know that. look up the definitions to vertex, symmetry, and direction of opening and go from there. any questions?
Use the Pythagorean theorem a^2+b^2=c^2
6^2+9^2=c^2
36+81=c^2
117=c^2
find the square root of 117
the answer is 11
Distributive because they are multiplying a number by a group of numbers added together is the same as doing each multiplication separately.
