1. what is the value of x? round the answer to the nearest tenth. the diagram is not drawn to scale. a)30
b)60
c)120
d)240

The correct option is B. 60°

Step-by-step explanation:

In ΔPCD and ΔPBA

PD = PA (radius of the same circle)

PC = PB (radius of teh same circle)

DC = AB (given)

So, By SSS congruency property of triangles,

ΔPCD ≅ ΔPBA

Now, By using CPCT property of two congruent triangles

m∠CPD = m∠BPA = 60°

⇒ x = 60°

Therefore, the correct option is B. 60°

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
