<span>In a triangle, the three interior angles always add to 180°.
56° + 72° + x° = 180°
128° + x° = 180° |subtract 128° from both sides
x° = 52°</span>
Answer:$.75 and $1.25
Step-by-step explanation:
X=white chocolate 4x+6y=10.50
y=dark chocolate 8x+3y=9.75
Both deal w/money solve using elimination.
4x+6(1.25)=10.50
4x+7.5==10.50
x=.75
-2(4x+6y=10.50)
8x+3y==9.75
-9y/-9=-11.25/-9
y=1.25
This is not possible to factor, atleast not in the format you posted it :)

Answer:
Length of the drain pipe is 72.15 feet.
Step-by-step explanation:
From the figure attached,
A drain pipe is to be laid between two pints P and Q.
Point P is 15 ft higher than the other point Q.
Angle of elevation of point P from point Q is 12°.
Let the length of pipe is l feet.
By applying Sine rule in the given right triangle PRQ,
Sin(∠Q) =
Sin(12) =
0.20791 =
l = 72.15 ft
Therefore, length of the drain pipe is 72.15 feet.
