sin 30 = 1/2 thus, we get 3/2 - 2cos 60 cos 60 = 1/2 thus we get 3/2 - 2/2 = 1/2 tan45 = 1 so the equation is just 4cos60 - 2cos60 cos 60 = 1/2, as previously mentioned thus, we get 2 - 1 = 1..... btw...I think you can just plug these functions into your calculator to figure t...

We are not given any other lengths or angles. It is impossible to determine the area of the triangle. x^2+y^2 = 65 we need to find 2xy

1 hour = 60 minutes 1 minute = 60 seconds so one hour = 3600 seconds this is 3600/8 = 450 times of the given. So in one hour, the car runs 450 * 40 = 18000 feet. 18000 / 5280 = roughly 3.4 miles To the nearest whole number, the car goes at 3 miles per hour.

We are not given the area, perimeter, or any other info to solve for x....Now if LMNO was a rhombus, that would be different.

I agree. Please explain what you came up with and how far you have gotten before posting 10 questions in a row.

multiply all by abcd to get bcd+acd+abd+abc = abcd.

Basically the inradius of the equilateral triangle. The formula for that is inradius * semiperimeter (half the perimeter) = area We know that the formula for calculating the area of a equilateral triangle is s^2 sqrt 3 /4 so we get 100sqrt3 as the area of the equilateral trian...

Please explain your logic before posting all the questions.

No you don't. FALSE, you find a common denominator, keep that denominator, and add the numerator.
Math
Could you please stop repeatedly posting a quadrillion questions and perhaps ask why you don't get the problem maybe? Anyway, False because many even numbers are negative.
