Find m< 1

a.30
b.33
c.57
d.63

The 3 inside angles of a triangle equal 180 degrees.

Angle 1 = 180 - 117 - 33 = 30

The answer is A. 30

A .30°

Step-by-step explanation:

In the given figure , we are given measures two angles of triangles as and .

The Angle sum property of triangle says that the sum of all the angles in a triangle is 180°.

Using Angle sum property , we have

   ∠1+117+33°=180°

⇒∠1+150°=180°  

⇒∠1=180°-150°=30°  [Subtract 150° from both sides.]

hence, the measure of m∠1 = 30°

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:
