so,
angle DAB = 25° + 35°
= 60°
now,
angle DAB + angle ADC. = 180°
or, 60° + ADC = 180°
or, ADC = 180° - 60°
Therefore, ADC = 120°
therefore, the angles of the PARALLELOGRAM are 60° and 120°.

Step-by-step explanation:
Answer:
The diver will be 8 feet from the end of the board when he hits the water.
Step-by-step explanation:
The diver hits the water when y = 0.
To find the distance, we have to find the values of x when y = 0.
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that
, given by the following formulas:
In this problem, we have that:
So
Then
It is a horizontal distance, so the answer is a positive value.
The diver will be 8 feet from the end of the board when he hits the water.
