cos2x = 1 - sin2x = 1 - 0.64 = 0.36
So cos x = +/- 0.6
Since x is acute, cos x is +ve, so cos x = 0.6
ba = 32 CD = 9x + 5 The best we can do in this case is write x in relation to it's original equation: x = (CD - 5)/9 because we have no way of relating a, b, c, and d from the given information.
0.5 Thanks Alc :)
Without knowing what the numbers are, I would suggest taking the mean of the given numbers.
PANT.
it equals to 8.10

Here is a non-conventional answer: -3 / 3 - 3 + 33 = 29 Use five 3's to write an expression whose value equals 29?
write two numbers that have the given absolute value. 1.4

The way I write the letter x the top and bottom angles are acute.
2 x 2 x 3 x 7 = 84
You would need a point ex: (4,5) y=5 if its a horizontal line you just write y=(value of y on the given point)
Count all the given numbers then count all the numbers of a given value. Divide one by the other and multiply by 100. For instance, if there are 50 numbers in total and 5 of them have the value 42, then the percentage of numbers with the value 42 is 5 / 50 * 100 = 10%.
Given point: (6, 7) Equation: 3x+y = 8 Parallel equation: 3x+y = 25
Wiki answer limits your ability to insert operators in questions, so please write out the word "equals" or "plus" as it is necessary.
it means to write the value. for example.... 1.639. just write the value.
