Let the supplement angle be x.
Supplement angles add up to 180:
x + x - 20 = 180
2x - 20 = 180
2x = 200
x = 100
Angle = 100 - 20 = 80
Answer: The angle is 80°
Answer:
122
Step-by-step explanation:
11x-65+58=180. The 58 comes from adding 29+29=58. You do this because there are two 29 due to it being an isosceles triangle meaning there are two sides equal.
Add your a like terms
11x-7=180
11x=180+7
11x=187
x=17
Plug the 17 in for 11x-65
11*17-65=122
You can change yourself by adding 29+29+122=180. You know this right because all triangles add to 180. '

Answer:
y=2x-3
Step-by-step explanation:
4x-2y=3
-2y=3-4x
2y=4x-3
y=4x/2-3/2
y=2x-1.5 m1=2 (the number near x)
If the searched line is parallel to the line 4x−2y=3, m1=m2= 2
y=m2x+b - the searched line
1=2*2+b
b=-3
y=2x-3
We're being asked to find the values of y for
for specific values of x. Basically, we are taking the cube roots of these numbers.
Answer:
-25/21
Step-by-step explanation:
m=(y2-y1)/(x2-x1)=(15-(-10))/(-15-6)=(15+10)/-21=25/-21
