Answer:
7
Step-by-step explanation:
The sum of the measures of the angles inside a triangle is 180°. Therefore, we can create the equation (6x+5)+60+73=180.
Then we simplify:
1. combine like terms. (6x+5)+60+73=6x+5+60+73=6x+138
2. 6x+138=180, -138 to both sides of the equation. the equation becomes 6x=42.
3. /6 to both sides of the equation. we can reach the conclusion that x=7
Answer:
(1,-4)
Step-by-step explanation:
x = -b/2a
a = 2
b = -4
x = 4/4
x = 1
Then substitute x = 1 into the equation to find y
y = 2(1)^2 - 4(1) - 2
y = -4
So, (1,-4)
