I dont know which math you are in but you can use the law of sins. (A/sin(a))=(B/sin(b)) where the capital letters are the sides (in this case you would put AC or whatever side length it is) and the lower case letters are the measures on the angles.
that may have been confusing but look up the laws of sines and cosine because you'll need to learn them and it's very helpful.
15/sin68 = x/sin88      x is the side BC and to get angle A, do 180-68-24
so x= sin88 (15/sin68)
so the answer to this question would be 16.17 cm

Please help me with this problem

To evaluate this expression, we simply plug the value of the variable into the expression and solve.

Since m = -4, plug a -4 in for m every time the m appears in the expression.

So we have (-4)^2 + 6(-4) + 3.

Start by simplifying the exponent.

(-4)^2 is 16.

Now multiply.

A positive times a negative is a negative.

So 6(-4) is -24.

So we have 16 + 24 + 3 which is 43.

Solve: -4.878-(-8.96)=
Pepsi [2]
-4.878-(-8.96) can be changed to -4.878 + 8.96 because when you subtract a negative it becomes a positive so the answer would be 4.082 or B
