It’s 20abcd because the product of 4&5 is 20 and their are no like terms with the letters so you just add them
Answer:
Correct option is
B
90
∘
,90
∘
,90
∘
Let AB and CD be two lines Intersecting at O, such that, ∠AOD=90
∘
Now, ∠AOD=∠COB=90
∘
(Vertically opposite angles)
⟹∠AOD+∠DOB=180
o
(Angles on a straight line)
⟹90+∠DOB=180
o
∠DOB=90
∘
∠DOB=∠AOC=90
∘
(Vertically opposite angles)
Thus, all angles are 90
∘
.
19=x+7
X=19-7
X=12
Therefore x is 12
Answer:
Step-by-step explanation:
Given a cone of base radius, r and perpendicular height, h
Since the height of a cone is twice the radius of its base.
The expression that represents the volume of the cone, in cubic units is .
If this is division for a remainder then your answer should be 1r9 but if its not with a remainder i have no idea
