d. Name a ray with endpoint E that is an opposite ray of . Solution a
A long session lasts 50 minutes.
Let,
Duration of long session = x
Duration of short session = y
According to given statement;
3x+4y=270 Eqn 1
each long session lasts twenty minutes longer than the short session.
x = y + 20 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 7
Putting y = 30 in Eqn 2

Since we already know c, so we need to find b.
c² = a² + b²
5² = 4² + b²
b² = 5² - 4²
b² = 25 - 16
b² = 9
b = 3
