Question:

Given the area of a triangle is 450 and and one of the angle is 45 degrees. Find the length of all three sides of the triangle.

Alex K.
Answer:

solving for the area, we get the value of x=30 using the equation 1/2x^2=450. Because we know one angle is 45 degrees, the other two must me another 45 degrees and a 90 degrees. Thus, using the properties of a 45, 45, 90 triangle, we can determine that the sides are equivalent having the value of 45 degrees and by using Pythagorean th. the last value is 42.43.

Question:

solve the equation 5(x-2)+3=4(x+5)-4

Alex K.
Answer:

This question can be solved by using the distributive property and multiplying the coefficients into the parenthesis. Then we combine like terms and move all the x values to one side of the equal sign and all the other values to the other side. We then solve for x and receive x=23.
