Six math problems need help?

Question

Dont need help with adding part for 1-5 just need to know what type of angle it is(acute,obtuse,right,straight)
1)12 degrees+37 degrees
2)117 degrees-11 degrees
3)45 degrees+45 degrees
4)130 degrees-68 degrees
5)53 degrees+106 degrees

6)show work
The water sprinklers rotated 56 degrees to the right.Then it rotated 24 degrees to the left and stopped.At what degree did the water sprinkler stop?

Answer 1

To help you, try to remember the following:



Acute angles are less than 90 degrees.

Right angles are exactly 90 degrees.

Obtuse angles are more than 90 degrees.

Straight angles are exactly 180 degrees.



So:



1) Acute

2) Obtuse

3) Right

4) Obtuse

5) Obtuse



I believe for number 6) that the sprinkler starts upright so if it rotates 56 degrees to the right, and then 24 degrees to the left the sum for where the sprinkler stopped would be 56 - 24 = 32 degrees. Drawing a diagram would help you here to work it out, start with an upright line, then measure 56 degrees to the right. Then see that by the sprinkler going back to the left by 24 degrees, it would take 24 off the 56 you have just drawn.



Hope that helps.

Answer 2

1.acute

2.obtuse

3.right

4.obtuse

5.obtuse

6. 56+24 =80 degrees which equals an acute angle
