Solution:

2(Perimeter of smaller triangle) = Perimeter of larger triangle

<u>Using the perimeter of the smaller triangle, solve for x.</u>

2(Perimeter of smaller triangle) = Perimeter of larger triangle
=> 2(3.5 + x + h) = 7 + 4 + 2h
=> 7 + 2x + 2h = 7 + 4 + 2h
=> 2x = 4
=> x = 2

The length of x is 2 units.

Equation : (7x-4)+(3x-3)+(x) = 180
In the equation the sum of the internal angle in the triangle is 180 degrees. Use this equation to figure the sum of angle in any quadrilateral 180*(number of sides-2)
Solve the equation
Put all similar variable on one side
7x+3x+x-4-3=180
11x-7=180
11x=180+7
11x=187
x = 187/11
x = 17
Now find the angles by plugging in x
Angle F (7*17-4) = 115 degrees
Angle G (x) = 17 degrees
Angle E (3*17-3) = 48 degrees
If you add 115+48+17 you will get a sum of 180 this shows your answer is right

Angle F = 115
Angle G = 17
Angle E = 48

Which is greater, 73 percent of 87, or 87 percent of 73?

Drupady [299]

87% of 73 is about 63.51 and 73% of 87 is 60.59 so 87% of 73 is greater
