The scale factor is 1/2 or a half
(x-9) (x+2)=x²+2x-9x-18=x²-7x-18
Answer:
C. x = 8 , y = 40
Step-by-step explanation:
since this is an Isosceles triangle 5x = 40° and x = 8
The sum of interior angles in a triangle is equal to 180°
40° + 5x + 2y + 20 = 180° add like terms
5x + 2y = 120
40 + 2y = 120 ➡ 2y = 80 and y = 40
Answer:
i think it's 10.6
Step-by-step explanation:
112 = x^2
