6,000 times 6,000 ten times or 6,000 times 6,000 squared maybe I'm not entirely sure sorry
290 mph , its going half the speed as before. Hope this helps.
I'm not sure but I would go with c
28 + 29 + 42 = 28 + 42 + 29 = 99
Commutative property: a + b = b + a
Since you know that PQ=RQ, you have an equilateral triangle. This makes things very simple.
Angle R should be the same as angle P.
A triangle is equal to 180 degrees.
Add angles P and R. Subtract 180 from the answer you got. That will give you 2a. a divided by 2 will give you a.
Or, since there are two right triangles, you can add 47 and 90. Subtract 180 from that and you will get a.
