A triangles angles measure up to 180° so before finding x you must find the missing angle.

So lets make an equation:

180=22+23+a

(a is the missing angle)

So add 22+23=45

180=45+a

Subtract 45 from both sides to isolate A

180-45=45-45+a

135=a

135° is your missing angle

So now we have to find X

A straight line measures to 180° so now we subtract 135°(or a) from 180°

180-135=x

x=45

Therefore X is 45°

yan [13]
X - Columbian coffee ( in pounds),
y - Brazilian coffee ( in pounds );
x + y = 100
8.85 x + 3.85 y = 6.55 ( x + y )
----------------------------------------
x = 100 - y
8.85 ( 100 - y ) + 3.85 y = 6.55 * 100
855 - 8.55 y + 3.85 y = 655
- 5 y = - 230
y = ( - 230 ) : ( - 5 )
y = 46
x = 100 - 46
x = 54
Answer: 54 pounds of Columbian coffee and 46 pounds of Brazilian coffee should be used.
