Answer:
80 : 100: 40: 140
Step-by-step explanation:
The four angles of a quadrilateral add to 360 degrees.
Ratio
4 : 5 : 2: 7
Multiply each by x
4x: 5x : 2x : 7x This total is 360 degrees
4x+5x + 2x+7x =360
18x = 360
Divide each side by 18
18x/18 = 360/18
x =20
The angles are
4x: 5x : 2x : 7x
4(20): 5(20) : 2(20) : 7(20)
80 : 100: 40: 140

Remember that the area of a triangle is defined by the formula:
( is the length of the base of the triangle and is the length of its height)
Substituting in the information the problem supplied us with, we find:
The length of the base of the triangle is approximately 13.02 inches.
