Answer:
Hank is correct
Step-by-step explanation:
With parallel lines intersected by the same line, all corresponding angles are equal. Also remember that the two angles the are formed on each line need to add to 180 degrees. So we can take the two given angle: 7x+10 and x + 10 and add them. x + 10 + 7x + 10 = 8x + 20 = 180
So Hank has the correct equation.
I believe it is the bottom left and bottom right answers.
Answer:
<u>C and D</u>
Step-by-step explanation:
<u>D.</u> A negative times a positive gives you a negative, so the first 2 fractions will still be negatives after they get out of the parenthesis
<u>C.</u> The 4/7 and -4/7 cancel out
The sum of the interior angles of all triangles is 180 degrees. This means you can set all the angles' expressions equal to 180 and solve algebraically for x.
180 = 3x + 2x + x
180 = 6x
30 = x
Answer:
30°
