solve for log_4 64
the answer is 3 because 4^3 is equal to 64
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.
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.
solve the equation 5(x-2)+3=4(x+5)-4
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.
