Dr. Newton needs 5000 dollars, and 3000 dollars have already been saved. So, 2000 dollars remain.
If these 2000 dollars must be saved withint 8 months, we can divide the amount needed by the time given, to find out that Dr Newton needs to save
dollars each month.
Answer:
y should be 5, when u solve for the angles u get 68+87+c=180, if c is y^2 then y is 5
Step-by-step explanation:
Draw an imaginary line from the vertex of angle x to the center of the circle.
This divides the 4-sided polygon into two right triangles. For example, the upper right triangle has an acute angle whose measure is 135 degrees / 2, or 67.5 degrees, and the another acute angle whose measure is x/2.
x/2 and 67.5 degrees are complementary angles, so x/2 + 67.5 deg = 90 deg. Thus, x/2 = 22.5 deg, and so x = 45 deg. (answer)
