I NEED HELP ASAP

Step-by-step explanation:

Find the last angle of the triangle.

The sum of all the angles in a triangle is 180 degrees.

Y+90+45=180

Y = 45

Find x:

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.

sin(B)=opp/hyp

rewrite as

x=7/Sin(45)

x = 7squareroot 2

Find the last side of the triangle using the Pythagorean theorem.

y=√(7√2)^2−(7)^2

y=7

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:

6/20
