Answer:
In a rhombus, the diagonals bisect at right angles. That means half the diagonals form a right angle triangle then we can try the Pythagorean theorem. so -
one side of triangle = 6/2 =3 (half of the diagonal)
other side = 8/2 = 4
a^2 + b^2 = c2
3 ^2 + 4^2 = c^2
9+16 = c^2
c^2=25
c = = 5
the hypothenus forms one side of the rhombus and here the hypothenus is 5, so the lenght of a side is 5 !
Answer:
A) 3/4
Step-by-step explanation:
Given: Both circle A and circle B have a central angle measuring 50°.
The area of circle A's sector is 36π cm2.
The area of circle B's sector is 64π cm2.
We know, area of the circle=
lets assume the radius of circle A be "" and radius of circle B be ""
As given, Area of circle A and B´s sector is 36π and 64π repectively.
Now, writing ratio of area of circle A and B, to find the ratio of radius.
⇒
Cancelling out the common factor
⇒
⇒
Taking square on both side.
Remember; √a²= a
⇒
⇒
⇒
Hence, ratio of the radius of circle A to the radius of circle B is 3:4 or 3/4.
Answer:
17
Step-by-step explanation:
Divide number of people by 42
676 ÷ 42 = 16.095...
16 × 42 = 672 , then
676 ÷ 42 = 16 remainder 4
Then another bus is required for the 4 if everyone is required
Thus a total of 17 buses are required
