Use the equation .8x + x = 252
x is the number, and .8 is the decimal equivalent of 80%.
1.8x = 252
x = 140
Answer:
? = 4
4 is the number missing on the right.
Step-by-step explanation:
Check out the 8 on left. It has become a 2 on the right. How did that happen?
What do you have to multiply the 2 by to get 8?
Before I answer, check out the 9 on the right. What did you have to multiply it by to get 36? The answer to that is 4 isn't it?
What about the 2. Don't you have to multiply it by 4 to get 8?
36 + 8 = 4(9 + 2) The distributive property on the right will produce the numbers on the left.
So ? = 4
Answer:
so what are we trying to figure out?
Step-by-step explanation:
Answer:
Step-by-step explanation:
take angle C as reference angle
using cos rule
cos C=adjacent/hypotenuse
cos C=21/75
cos C=0.28
C=
0.28
C=73.7 degree
