Answer:
x=15
Step-by-step explanation:
so we are given one angle 90, although x is used in both so you can add them. We know that the sum of angle measures in a triangle is 180 so the equation is: 90+6x=180
subtract 90 from both sides: 6x=90
divide by 6: x=90/6
simplify: x=15
You have to graph your coordinates before you do anything else
Answer:
obtuse
Step-by-step explanation:
Answer:
The slope is -1
Step-by-step explanation:
You can use the find slope form using two different points like (0,1) and (-1,0)
0 -1 = -1, 1 - 0 = 1, -1/1 = -1
The slope is -1
Answer:
a > -2
Step-by-step explanation:
-12a +7<31
Subtract 7 from each side
-12a +7-7<31-7
-12a <24
Divide by -12, remembering to flip the inequality
-12a/-12 >24/-12
a > -2
