Answer:
Is not the answer but is how to do it. Sorry
Step-by-step explanation:
you got the value of a=2
use the formula
S=n/2 [2a+(n-1)d] then calculate d from here..
put it in t=a+(n-1)d
ANSWER
The greatest common factor is 5b.
EXPLANATION
The first expression can be rewritten as
The second expression is rewritten as
The third expression is
The greatest common factor is the product of the least powers of the common factors.
Answer:
17+5=17+5
No matter what order you put them it will always be the same
6ba is the answer you need
Answer:
See attached for the cyclic quadrilateral
To prove: <BAD + <BCD =180°
Construction: Join B and D to the centre O of circle ABCD
Proof
With the lettering of the attached drawing,
<BOD = 2y (angle at centre is 2 X angle at circumference)
Reflex <BOD = 2x (angle at centre is 2 X angle at circumference)
∴ 2x + 2y = 360° (angle at point)
∴ x + y = 180°
∴ <BAD + <BCD = 180°
Step-by-step explanation:
The vertices of a cyclic quadrilateral lie on the circumference of the circle and the opposite angles of a cyclic quadrilateral lie in opposite segment of a circle.
The question is to prove that the opposite angles of a cyclic quadrilateral are supplementary that is 180°. Another way of stating this theory is 'Angles in opposite segments are supplementary'.
Note that the sum of supplementary angles is 180°.
