Answer:
4
Step-by-step explanation:
Divide 28 by 7 and get 4.
C = 11m c + m = 60
Substitute
11m + m = 60
12m = 60
m = 5
Since we are asked to find DF, and we are given an angle and the side opposite to it, we can use the sine function to find DF.
let x be the length of side DF.
sin(32)= 17/x
x= 17 / sin(32)
x= 32.08
approximately 32.1
Answer: ∛v
Step-by-step explanation:
Since we know volume is measured height x width x length, we know the equation we'd use here would be:
___ x ___ x ___ = v in³
If this was area, we would have ___ x ___ = v in², and it would be easy to find each blank. You would just find the square root of "v", making your answer √v.
When you have 3 things multiplied by each other (that are exactly the same, which is the situation here since this is a cube), you will want to find ∛x (if x is our unknown variable). This means that we are finding ONE-THIRD of the number ... sort of. So if x was equal to 8, then ∛x = 2, because 2 x 2 x 2 = 8.
In our situation here, x = v, and since we don't know the actual number, we will keep it as a square root, so the answer to your question is ∛v.
I really hope I was able to explain easy enough, feel free to ask anything else!
Answer:
42.5units^2
Step-by-step explanation:
Area of a trapezium=1/2 *(a+b) height.
a=5 units
b=12units
height=5units
Area=1/2*(5+12)*5
Area=1/2*17*5
Area=1/2*85
Area=42.5units^2
