Alright not entirely sure but here is my theory
69x100=690 if he has the 11$ interest rate it would be 701$ in 10 months
so he would have 1 more dollar <span />
Answer:
X=24, Y=7
Step-by-step explanation:
We use the concept of similarity.
By observing the figure, we notice that the hypotenuse is 50, and the hypotenuse of the smaller triangle is 25.
That means the hypotenuse of the larger triangle is double the hypotenuse of the smaller triangle. Meaning, the other sides of the larger triangle would be double the smaller sides of the smaller triangle.
We already have the sides of the larger triangle, divide them by two to get x and y.
X = 48/2 = 24
Y = 14/2 = 7
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
