- ∠ABD = 35°
- ∠DBC = 35°
- ∠ABC = 70°
Step-by-step explanation:
When the question says a line bisects an angle which means that this line is cut exactly at the centre of an angle so both angles will be the same :
Question 21,




Question 22,


Question 23,








Volume of a cylinder = cross sectional area x height of the cylinder
So, 1728 = 3.14 x (r)^2 x 22
1728 = 69.08 x r^2
r^2 = 25.01
r = 5.00 cm

Answer: 8 times
Step-by-step explanation:
There are 1/6 chance everytime you roll, so if you x48 is is 48/6 which is 8 times!
Step-by-step explanation:
4x + y = 6 => 8x + 2y = 12.
8x + 2y = 12
+ (-5x - 2y = -3)
=> 3x = 9, x = 3.
Therefore 4(3) + y = 6, 12 + y = 6, y = -6.
The solutions are x = 3 and y = -6.
