Answer:
The trapezoid is D
Step-by-step explanation:
I learned this in 3rd grade
This is the concept of trigonometry, the value of x will be calculated as follows;
sin theta=[opposite]/[hypotenuse]
theta=x
opposite=16 units
hypotenuse=21 units
thus;
sin x=16/21
hence;
x=arcsin(16/21)
x=49.63
x=50 (to the nearest degrees)
Answer:
0 handshakes
Step-by-step explanation:
There are 8 women of different heights.
Let the eight women be A, B, C, D, E, F, G and H
Assume A is taller than B and A decides to shake hands with B, B will refuse because A is taller. If this happens across the eight women then there will be 0 hand shakes.
If this assumption is taken out, we have 7+6+5+4+3+2+1 = 28
Answer:
Step-by-step explanation:
The question seeks to examine the knowledge of the concept of perimeter of a square.
A perimeter is the sum total of the distance of all the lengths of the sides of a shape or object in context.
Step 1: Scale the object.
Assume 1 cm = 1 tiny graph square
We can say that in object (Square) ABCD; length AB = BC = CD = AD = 4cm
Step 2: solve for the perimeter.
Formula for the perimeter of a square is = 4 × length
Perimeter= 4 × length
Perimeter= 4 × 4cm
Perimeter= 16 cm.
All you have to do is find a least common multiple for 6 and 8 in this case it would be 24 because 6's multiples are 6,12,18,24 and 8's multiples are 8,16,24 and many more but these are the lcm so in it would be
morning- 20/24
and
afternoon - 15/24
the answer is the morning
