No. Just because the angles are all less than 90 degrees, that doesn't tell us anything about the sides. The sides are all congruent ONLY if all 3 angles are 60 degrees each. If the angles all have different sizes, then so do the sides.
Answer:
Area=2232 square ft
Perimeter=206 ft
Step-by-step explanation:
given
the diagram is a rectangle
length=72 ft
width=31 ft
we know that
formula of the area of rectangle= length × width
Area=72×31 square ft
Area=2232 square ft
Now calculate the perimeter
perimeter of rectangle=2(length+width)
perimeter=2(72+31)
perimeter=2(103)
perimeter=206 ft
Cos m = .4685
cos^-1(.4685) = 62 degrees
angle L = 180-90-62 = 28 degrees
Answer:
She has 6 hours left.
Step-by-step explanation:
She started with 3 hours saved and got 2 more hours for each day that she did her chores and ate her vegetables. Since she did her chores and ate her vegetables 4 days that means that in total she gained 8 hours (4 * 2) plus the ones she already had saved. So 8 + 3 = 12 - 6 = 6

To find out if a number is prime or composite, divide the number by 2. If it gives no remainder, it is a composite number. Otherwise, it's a prime number.
83 / 2 = 41 R 1
It has a remainder, so it's a prime number.
