Answer: 85
Step-by-step explanation: 15 × 6= 90 - 5= 85
You have two 30-60-90 triangles, ADC and BDC.
The ratio of the lengths of the sides of a 30-60-90 triangle is
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
Using triangle ADC, we can find length AC.
Using triangle BDC, we can find length BC.
Then AB = AC - BC
First, we find length AC.
Look at triangle ACD.
DC is the short leg opposite the 30-deg angle.
DC = 10sqrt(3)
AC = sqrt(3) * 10sqrt(3) = 3 * 10 = 30
Now, we find length BC.
Look at triangle BCD.
For triangle BCD, the long leg is DC and the short leg is BC.
BC = 10sqrt(3)/sqrt(3) = 10
AB = AC - BC = 30 - 10 = 20
Answer:
False
Step-by-step explanation:
6*2= 12
So to get common denominators, you would need to divide 5/12 by 2 OF multiply 2/6 by 2
For the sake of ease just multiply 2/6 by 2, this will equal 4/12 NOT 5/12
Hope this helps! :)
