Since LM = AM, point M must be on the perpendicular bisector of AL. Since AM = BM, BL must be perpendicular to AL. This makes ∆ALC a right triangle with hypotenuse AC twice the length of side AL. Hence ∠LAC = ∠LAB = 60°, and AL is angle bisector, median, and altitude.

ΔABC is isosceles with ∠A = 120°, and ∠B = ∠C = 30°.

PLEASE HELP!!! I cannot figure this problem out.

nataly862011 [7]

Answer:

A and C.

Step-by-step explanation:

to get rid of the square root & n, you would have to multiply it by n on both sides of the equation, giving you r^n=a.

also to get rid of the square root & n, you can also multiply both sides of a and r by the exponential fraction with n as the denominator:

$\sqrt[n]{a} =r \\(a)^\frac{1}{n} = r\\a\frac{1}{n} = r$

Are 6/10 and 6/30 multiples of 3/10 ? explain

Alex Ar [27]

6/30 and 6/10 are not multiples of 3/10 because you cant take 3/10 and multiply both the numerator and the denominator by one number and get 6/30 or 6/10 but a multiple would be like 6/20, 18/40, 30/100 and so on.
