Answer:
x = 20°
Step-by-step explanation:
4x + 10 = 90
4x = 80
x = 20
since r is positive, the correlation is also positive also, since r is closer to 0 than 1, the correlation is weak
Answer:
The answer to your question is x = 3
Step-by-step explanation:
Data
m∠2 = 10x + 10
exterior angle = 110°
x = ?
Process
1.- Find the measure of the angle supplementary to the angle 110°. It will be angle y.
180° = 110° + y
- Solve for y
y = 180 - 110
y = 70
2.- From the picture we conclude that the triangle is Isosceles because two of its sides measure the same.
In an Isosceles triangle two of its angles measure the same so,
180° = 70° + 70° + ∠2
- Solve for ∠2
∠2 = 180 - 70 - 70
∠2 = 40
3.- Find x
10x + 10 = 40
Solve for x
10x = 40 - 10
10x = 30
x = 30/10
x = 3
C it’s wrong so don’t listen to me
True the n is usually where the number would go like the a100th term 100 would be n :)
