what number must be added to both numerator and denominator of 16/21 to make the resulting fraction equal to 5/6?

1 answer:

4 0

9 because 16 plus 9 is 25 and 21 plus 9 is 30. now you have 25/30
Now you have to simplify:

25 divided 5 is 5 and 30 divided 5 is 6. So 5/6

The area of parallelogram WXYZ is approximately 45 square units.

neonofarm [45]

Answer:

Option (4)

Step-by-step explanation:

Area of a triangle = $\frac{1}{2} (a.b.\text{Sin}\theta)$

Where a and b are the sides of a triangle and θ is the angle between the sides a and b.

By this rule,

Area of ΔWZY = $\frac{1}{2}(\text{WZ}).(\text{YZ}).\text{Sin}(115)$

45 = $\frac{1}{2}(\text{YZ}).(10).\text{Sin}(115)$

9 = (YZ).Sin(115)°

YZ = $\frac{9}{\text{Sin}(115)}$

YZ = 9.93

Perimeter of parallelogram WXYZ = WX + XY + YZ + WZ

= 9.93 + 10 + 9.93 + 10

= 39.86

≈ 40 units

Therefore, perimeter of the parallelogram is 40 units.

Option (4) is the answer.
