My teacher told be to try and think of it as a circle, because circles are 360 degrees. Then to place those angles in the circle and it should make it easier to find the angles, because when you see it in the circle, you can divide it into 4 parts so that you would then have 4, 90 degree angles that you can then work off of by placing those angles you need to find into the circle. It was supposed to make it easier, and i genuinely hope that you can do this. You got this, and you will get through the pain of math tonight and many more. Good luck. ^-^

Vertical: opposite from each other (will have same degree)
Alternate exterior: the angles outside that are opposite of eachother (will have same degree)
Alternate interior: angles inside that are opposite of eachother (will have same degree)
Corresponding: the angle on the same side at the same level (will have same degree) example for corresponding: use picture for this question: giving angle 1 the corresponding angle will be 5 why?? They are both above the dividing line and are left of the parallel lines j and k
4. v 1,4 5,8 3,2 7,6
5. ae 2,7 1,8
6. ai 3,6 4,5
7. C 1,5 3,7 4,8 2,6

8. Angle 1 = 135 Given* other angle will be 45 *
Angle 2= 45 supplimentary angle add up to 180 (1,2)
Angle 3= 45 supplumentary angles add up to 180 (1,3)/ vertical angles =each other (2,3)
Angle 4= 135 vertical angles = each other (1,4)
Angle 5= 135 complimentary angles = each other (1,5)
Angle 6= 45 corresponding angles = each other (6,2) alternate interior angles = each other (3,6)
Angle 7= 45 corresponding angles = each other (3,7) alternate exterior angles = each other (7,2)
Angle 8= 135 alternate exterior angles= each other (1,8) hope that's not too confusing let me know if this helped

What is the sum?<br> 8+(-12)<br> О-20<br> 0-4<br> 020
rodikova [14]

Answer: -4

Work: So, to get -4, we need to simplify the equation. If you see any equation with +(- that's subtraction. So, with the rule, this equation is basically 8-12, and that's -4.

Simplify the following using PEMDAS: [3−(3⋅3)+33÷3] × 4⋅5/10−2⋅3
kompoz [17]

Answer: 34

Step-by-step explanation:

<u>Given expression</u>

[3 - (3 · 3) + 33 ÷ 3] × 4 · 5 / 10 - 2 · 3

<u>Simplify by parentheses in the bracket</u>

=[3 - 9 + 33 ÷ 3] × 4 · 5 / 10 - 2 · 3

<u>Simplify by multiplication</u>

=[3 - 9 + 33 ÷ 3] × 20 / 10 - 6

<u>Simplify by division</u>

=[3 - 9 + 11] × 10 - 6

<u>Simplify by bracket (addition/subtraction)</u>

=[-6 + 11] × 10 - 6

=[4] × 10 - 6

<u>Simplify by multiplication</u>

=40 - 6

<u>Simplify by subtraction</u>

=\boxed{34}

Hope this helps!! :)

Multiply 6√3 • 8√14 • √10 • √2
uranmaximum [27]

Answer:

96 sqrt(210)

Step-by-step explanation:

6√3 • 8√14 • √10 • √2

We multiply what is outside the square roots with what is outside the square roots  and what is inside the square roots with what is inside the square roots

6*8 = 48

3*14*10*2 = 840

6√3 • 8√14 • √10 • √2

48 sqrt(840)

48 sqrt( 4*210)

sqrt(a*b) = sqrt(a) sqrt(b)

48 sqrt(4) sqrt(210)

48 *2 sqrt(210)

96 sqrt(210)

210 is 3*7 *5*2  which are all primes, so we cannot simplify the sqrt (210)
