Answer:
9) x = gy/c, 11) a = np/m
Step-by-step explanation:
9) g = xc/y
g*y/c = xc/y *y/c
gy/c = x
11) am = np
am/m = np/m
a = np/m
Answer:
the answer is 2.2
Step-by-step explanation:
I used a calculator
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
Y2-y1 over x2-x1 (slope intercept form)
Answer:
C. -2(9 + 32n)
Step-by-step explanation:
-2(9 + 32n)
= -2*9 - 2*32n
= (-18) - 64n.
