YOU HAVE TO FIND THE SLOPE m
The formula to find the slope is m=(y₂-y₁)/(x₂-x₁)
Since we have the coordinate of each point, then we can calculate the slope m
7) (-6-3)/(2+4) = -9/6 =-3/2 (slope negative so the function falls
8) (-1-1)/(7-7) = -2/0 (tan ---> ∞ ) VERTICAL
9) (-2+2)/(5-3) = 0/2 = 0 slope = 0 ===> Horizontal
Step-by-step explanation:
m< AOC = 90°
m< AOB +m<BOC = 90°
6x-12+3x +30 = 90°
9x +18° = 90°
9x = 90- 18° = 72°
x = 8°
m<AOB =6(8)-12 = 48-12 = 36°
Answer:
68
Step-by-step explanation:
All sides of a rhombus are equal.
Answer:
52º, 128º
Step-by-step explanation:
8. Because ∠6 is an opposite angle to ∠5, ∠6=∠5=52º;
9. Because line a//line b, ∠6=∠4=52º, so ∠7=180º–52º=128º
