Y is a 97 degree angle
Angle z is 83 because the sum of all interior angles in a triangle is 180
180-55-42 = z
83 = z
Angles y and z are supplementary angles, so they add up to 180.
Since z = 83 and 180 - 83 = 97, angle y is 97 degrees
Answer:
, solution is $14.29
Step-by-step explanation:
We can create an equation for this scenario to try and solve it.
Assuming the cost of the CD is x, it’s sale tax will be 0.05x (as that is 5% of x, 0.05.)
We can write the equation in two ways:
or .
Assuming we take the second one (easier to work with), we can divide both sides by 1.05. The equation simplifies to x = 14.289... which rounds to x = 14.29.
Therefore, the equation is and the solution is $14.29.
