Answer:
1. Question isn't complete. It says "Which gives the first two steps to evaluate" and cuts off.
2. Seems like 3.(4-2)2+1 if 3. means to multiply.
3. 9.1=9 should be the answer if . means to multiply.
4. 10x+0=10x
5. x=3 or y=-8
6. x=5 or y=-6
7. Not so sure about this one.
8. 7x/9y
9. 5
Step-by-step explanation:
2. 3.(4-2)2+1
3(2)2+1
6(2)+1
12+1
13

First of all I want to point out you drew the diagram a little wrong. The Arc is 41 doesn't mean its 41 degrees it means it has length 41 so remove the degrees symbol.
Now for the answer the other arc have to have angle 40 too because vertical angles. And because the radius is the same, both of the length has formula 40/360*pi*2*radius which is 41 in this case. So x has to be 41 also :) Done!
84 is a composite number. 84 = 1 x 84, 2 x 42, 3 x 28, 4 x 21, 6 x 14, or 7 x 12.
Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.
You need the Law of Cosines here and you use it when you have 2 sides and an enclosed angle. The side across from the angle is the one we are looking for. The correct way to express the Law using what we have is the last choice above. Side RT is the unknown, and it is across from the angle that is enclosed between the 2 other sides.
