Answer:
-0.43765943877
Step-by-step explanation:
-0.40178571428 (-4.5 / 11.2 )
then you do minus 4.5
-4.90178571429
then divided by 11.2
-0.43765943877
2 supplementary angles when added together need to equal 180 degrees.
Add:
3x-23 + 2x-12 = 180
Simplify:
5x -35 = 180
Add 35 to both sides:
5x = 215
Divide both sides by 5:
X = 43
Now replace x with 43 in the equation for angle b:
2(43) -12 = 86-12 = 74 degrees
Angle B = 74 degrees
Answer:the Length is 22.5 inches, and width is 7.5 inches.
Step-by-step explanation:
Step 1
The perimeter of the rectangle is given as
P = 2L + 2W
We were given tha length is 3 times the width,
so L = 3 W
Replacing L by 3W in the equation of the perimeter becomes
Step 2
P = 2L + 2W
2(3W) + 2W = 60
6W + 2W = 60
8W =60
W = 60 /8
W = 7.5
Snce L = 3W
L= 3 (7.5)
L = 22.5
Therefore the Length is 22.5 inches, and width is 7.5 inches.
