Answer: 45
Step-by-step explanation:
Sum is addition so it would be
28+17=45
Answer:
What the hell AC is not given so you can't find the Perimeter
Step-by-step explanation:
x+10=0
x=-10
AB=x+5
AB=-5
BC=x-2
BC=-12
Area of ABC = 30cm2
<u>Perimeter of ABC = AB+BC+</u><u>AC</u>

2/5-1/4
8/20 - 5/20
(8-5)/20
= 3/20
I hope that's help ! if you have question please ask
Step-by-step explanation:
We can prove the statement is false by proof of contradiction:
We know that cos0° = 1 and cos90° = 0.
Let A = 0° and B = 90°.
Left-Hand Side:
cos(A + B) = cos(0° + 90°) = cos90° = 0.
Right-Hand Side:
cos(A) + cos(B) = cos(0°) + cos(90°)
= 1 + 0 = 1.
Since LHS =/= RHS, by proof of contradiction,
the statement is false.
Answer:
It is 
(12 × 4) = 24
Step-by-step explanation:
