20% of 65 = 65 * 1/5, which is 13. so 20% of 65 is $13. so a discount of 20% = 65-13 which is $52
Answer: B
Step-by-step explanation:
Histogram is a statistical graph with the use of bar. The bar are not seperated unlike bar chart.
0.320 to 0.329 and 0.360 to 0.369 are of the same frequency which is equal to one. 0.350 to 0.359 is of frequency 2 a little above frequency 1.
Option B and D are very close to each other in value representation. But the frequency of 0.350 to 0.359 in option D is 3. This renders option D invalid and make option B the correct answer.
Given:
AD is an angle bisector in triangle ABC.
.
To find:
The value of
.
Solution:
AD is an angle bisector in triangle ABC.



According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
Using angle sum property in triangle CAD, we get





Therefore, the angle of angle ADC is
.
