When you multiply a value by 2/3, you are finding 2/3 of that number, so your new length would be 6 and your new width would be 4. The original area was 9 × 6 = 54, and the new area is 6 × 4 = 24. 54 ÷ 24 = 2.25, or 2 1/4, so your answer is 2 1/4, which as an improper fraction is 9/4. I hope this helps!
Answer:
C, 42 degrees
Step-by-step explanation:
Considering angle BAD is 60 degrees, that makes angle BCD also 60 degrees. Since parallelograms have 360 degrees in total, we're still missing 240 degrees. Since angles BAD and BCD are congruent (equal), that means that angles ABC and ADC also have to be congruent. To find their angles, we do 240 divided by 2, which equals 120. Now that we know all of the angles, lets focus on angle ADC. Since angle 1 has been given to us, all we need to do is subtract 78 from 120 which turns out to be 42 degrees, which is the answer.
We need at least 3 informations.
They are similar to that of the requirements for the two triangles to be congruent.
1. Angle - Side - Angle
2. Side - Angle - Side
3. Angle - Angle - Side (this one is not easy for drawing)
4. Side - Side - Side and
5. Right angle - Hypotenuse - Side
