Answer:
a. m<A = 35°
b. m<CBD = 61°
c. m AD is sin55 = AD/40 AD = 32.77
d. m BC is sin 29 = 22.94/BC BC = 47.32
e. m CD is tan 29 = 22.94/CD CD = 41.38
f. m BD is cos 55 = BD/40 BD = 22.94

Answer:
<u>If the width is 23 meters, the perimeter of the rectangle is 100 meters, or if the width of the rectangle is 0.23 meters, the perimeter is 54.46 meters.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Length of the rectangle = 27 meters
Width of the rectangle = 23 meters or 0.23 meters (it's not clear)
2. We will calculate the perimeter for any of the two possible values of the width of the rectangle, this way:
Perimeter of the rectangle = 2 * Length + 2 * Width
Replacing with the values we know:
Perimeter of the rectangle = 2 * 27 + 2 * 23
Perimeter of the rectangle = 54 + 46 = 100 meters
Perimeter of the rectangle = 2 * 27 + 2 * 0.23
Perimeter of the rectangle = 54 + 0.46 = 54.46 meters
Answer:
26.1 repeated
Step-by-step explanation:
Answer:
a is correct
Step-by-step explanation:
it is correct because we are adding
Use the quadratic formula .
x^2-2x+11=0
a=1
b=-2
c=11
x=-2+- (-2)^2-4*1*11 divided by 2
x=2+- the square root of -40 divided by 2
There is no real solutions
