Let the number in the Spanish Class = x
Then the number in the Geometry Class = (4/5) x
Equation
x + (4/5)x < 54
Solution
x + (4/5)x < 54
4/5 = 0.8
x + 0.8x < 54
1.8x < 54 Divide both sides by 1.8
1.8x / 1.8 < 54/1.8
x < 30
The sign used in the equation is less than, not less than or equal to.
The number of students taking Spanish cannot equal 30. There must be 29 in the Spanish Class.
Acute angles are less than 90 degrees. So we can rule out 90 and 123. We also have the clue that it is a right triangle. Therefore we know two angles and can use the following equation to find the answer.
90+57+x=180
147-147+x=180-147
x=33
Therefore the answer is 33 degrees. Your welcome ;)
