Step-by-step explanation:
We know that m∠1 is 110°. If we look at m∠7 closely, we can see that while m∠1 is an obtuse angle (greater than 90° but less than 180°), m∠7 is an acute angle (less than 90°).
Now, we can eliminate 110° and 180° since we know that m∠7 is an acute angle. There are only 2 choices now: 40° or 70°.
If you flip the image around, you can see that the angle is slightly less than 90°, so it has to be 70°.
Answer:
2) 70°
The area A of a circle is equal to: pi times the radius squared
A = πr²
A = π5², which is 78.5
Answer:
1
Step-by-step explanation:
y = mx+b where m is the slope and b is the y intercept
y = -3x +3
We want to find the x intercept
Set y = 0 and solve for x
0 = -3x+3
Subtract 3 from each side
-3 = -3x
Divide each side by -3
-3/-3 = -3x/-3
1 =x
Answer:
-31
Step-by-step explanation:
you have to get the variable on one side alone. so you would add the -7 to the 24 then divide by -1 because you have a -x when adding the -7 to the 24
