Answer:
x=70
Step-by-step explanation:
The value of x is 70 because this triangle is isosceles, meaning that there are two congruent sides and two congruent angles (which are the base angles). x is one of the base angles, 70º is the other base angle's measurement, so x=70.
Answer:
x = -1, y= -5
Step-by-step explanation:
y=-x-6
y=x-4
Since both equations are equal to y we can set them equal to each other
-x-6 = x-4
Add x to each side
-x-6+x = x-4+x
-6 = 2x-4
Add 4 to each side
-6+4 = 2x-4+4
-2 =2x
Divide by 2
-2/2 = 2x/2
-1 = x
now find y
y = x-4
y = -1-4
y = -5
What I see is that they are multiplying by 5 so the last one is 10 x 5 which equals 50!
