Find the measure of the indicated aces and angles

Mathematics
1 answer:
Serggg [28]3 years ago
4 0

Answer:

a=21

b=69

c=42

d=138

Step-by-step explanation:

c is supplementary to d (which is 138), so c=180-138= 42.

angle b is on the edge of the central angle 138, so b is 1/2, therefore, b=69.

angle a is complementary to angle b because any triangle that includes the diameter is a right angle, so angle a=90-69=21.

Betty sets up a lemonade stand and charges $1 per glass. It cost her $50 to set up the stand. Which function gives the profit, p
wariber [46]

Answer:

p = g - 50

Step-by-step explanation:

profit = income - expenses

income = 1 * g = g

expenses = $50

p = g - 50

If g = 50, then

p = 50 - 50 = 0

If she sells 50 glasses of lemonade, she breaks even. That means she makes no profit, but also she loses nothing.

If she sells more than 50 glasses, then she makes a profit.

The two triangles are congruent through AA (angle-angle proportionality theorem) therefore all the sides are congruent to each other.

In this case:

2y = 5y - 7

2y - 5y = -7

-3y = -7

y = -7/-3

y = 7/3
