Answer:
A
d = 2
Step-by-step explanation:
<em><u>Formula</u></em>
l = a + (n - 1)d
<em><u>Givens</u></em>
n = 10
a = - 5
l = 13
<em><u>Solution</u></em>
13 = - 5 + (10 - 1)d Substitute
13+5 = -5+5 + 9d Add 5 to both sides
18 = 9d Divide by 9
18/9 = 9/d
d = 2
Answer:
Option 3, angle 2 is equal to 37 degrees
Step-by-step explanation:
Angle 2 is on the opposite side of the 37 degree angle, so it is also 37 degrees
You need to multiply 10.35 * 9 and that will give you your answer.
Answer:
x =147
Step-by-step explanation:
The sum of the angles is = 360 -(2x+1) ( since it will make a full circle)
42+(-124+x) =360-(2x+1)
Combine like terms
x-82 =359-2x
Add 2x to each side
x-82+2x = 359
3x -82 = 359
Add 82 to each side
3x-82+82 = 359+82
3x = 441
Divide by 3
3x/3=441/3
x =441/3 or 147
