What is the value of c? A.100 B.50 C.84 D.80
2 answers:
Answer: The correct option is (C). 84.
Step-by-step explanation: We are given to find the value of c in the figure.
We know that,
in a cyclic quadrilateral, the sum of the measures of opposite angles is 180°.
We can see that in the given figure,
the angles with measure c° and 96° are opposite to each other.
Therefore, we get
Thus, the required value of c is 84.
Option (C) is CORRECT.

Answer:
y = - 400 + 700x
Step-by-step explanation:
Nour's altitude increased at a constant rate from the Dead Sea up to Amman.
Initially, her altitude was 400 meters below from the sea level and then she arrived at an altitude was 1000 meters above sea level arrived to Amman, 2 hours later.
So, she moves (400 + 1000) = 1400 meters in 2 hours.
Therefore, her rate of change of altitude is meters per hour.
Therefore, if y represents Nour's altitude in meters relative to the sea level after x hours then the relationship between the altitude and number of hours is given by
y = - 400 + 700x (Answer)
