Mathematics
1 answer:
balandron [24]3 years ago

Answer:

(2) angle1 = 139, angle2 = 41, angle4 = 41, angle5 = 139, angle6 = 41, angle7 = 139, angle8 = 41

(3) angle1 = 150, angle2 = 30, angle4 = 30, angle5 = 150, angle6 = 30, angle7 = 150, angle8 = 30

Step-by-step explanation:

All angle are either equal to each other or supplementary.  I use corresponding angles and vertical angles to prove each of the above.

For number 3, angle 3 and angle 8 are supplementary, so they add up to 180:

8x +70 + (4x - 10) = 180

12x + 60 = 180

12x = 120

x = 10

So if x = 10, then 8x + 70 = 8(10) + 70 = 150

That means all angles are either 150 or 30 for number 3.

Answer: It is a 90 Clockwise Degree Turn.

Step-by-step explanation:

From my knowledge, a 90-degree turn is a turn to the right.

So if you turn the "C" in the Y-axis 90 degrees you will get The "C" on the X-axis.

For Example: When you walk around a street you either turn 90 degree's to the right or 90-degrees to the left.

Hope this Helps!
