You multiply length times width or base times height.
100 + 50 + 3 + 7/10 + 6/100
1.
Since ABCD is a rectangle, then
angleABE = 90 degrees
angle ABE + angle BEA + 41 = 180
Substitute the known and solve for angle BEA
angle BEA + 41 = 90
angle BEA = 49 degrees
But,
x + angleBEA + 61 = 180 (angles in a straight line)
x = 180 - 61 - 49
x = 70 degrees
2.
triangle XYZ is equilateral, meaning all angles in it are the same, each 60 degrees.
Therefore,
Angle YZX = 60
But Angle YZX = x + 32 (exterior angles equal to the sum of the two opposite interior angles)
60 = x + 32
Therefore,
x = 28 degrees
3.
Angle QPR = Angle QRP (equal oppo sides, equal opposite angles)
Therefore, 2angleQRP + 64 = 180 (angle sum of a triangle)
Angle QRP = 58 degrees
But angle QRP = x + 35 (exterior angles equal to the sum of the two opposite interior angles)
58 = x + 35
x = 23 degrees
J, (8,-3) because since they are diagonals, you can take the x and y values between the vertices and point of intersection.
For x
The distance between 2 and -4 is 6. Moving 6 in the other direction results in an x value of 8 (2+6)
For y
The distance between 5 and 1 is 4. Moving 4 in the other direction gives you a y value of -3 (1-4)
The answer is therefore (8,-3)
