One easy way to understand it,is to turn the whole number into a fraction
The area of the rectangle:
A = Length x Width = JK x KL = 36 cm²
If JK ≥ 4 cm, we have to prove that KL ≤ 9 cm.
Answer:
Assume that a. KL > 9 cm.
Then the area of rectangle JKLM is greater than b. 36 cm²,
which contradicts the given information that c. side is at least 4 cm long.
So the assumption must be false. Therefore, d. KL ≤ 9 cm.
This is your answer, good luck buddy
Answer:
60 degrees.
Step-by-step explanation:
A full rotation is 360 degrees.
So 1/6 is 360 * 1/6 = 60 degrees.
Cosine again. Yay.
Put 36 into a fancy calculator with one of those cos() things. You get about 0.81.
So that's the ratio between x and 10.
So basically x/10 = 0.81, or 0.81 * 10 = x.
8.1 = x
