I’m confused..what do we examine?
The answer is B.12 because if she make 3 in 5 hours that means that in twenty hours should make 12 because it's like this 3 x 4 = 12 and 5 x 4 = 20 so when you add the hours up you'll get the answer
W=2L-5
-------------
A=L*W
=L(2L-5)
=2L²-5L
-------------
dA/dL=4L-5
When dA/dL=0,
4L-5=0
4L=5
L=5/4
----------------
When L=5/4
A=5/4*(2*(5/4)-5)
=5/4*(10/4-20/4)
=5/4*((-10)/4)
=5/4*(-5/2)
=-25/8
--------------------------------
*You may have been given a badly written out question. The answer doesn't make sense.
The measure of angle A is 65°
Explanation:
Given that ABCD is a quadrilateral inscribed in a circle.
The measure of angle A is 
The measure of angle B is 
The measure of angle D is 
We need to determine the measure of angle A.
Since, we know that the angles B and D are opposite angles and the opposite angles of a quadrilateral add up to 180°
Thus, we have,

Substituting the values, we have,


Thus, the value of x is 32°
Substituting the value of x in the measure of angle A, we get,




Thus, the measure of angle A is 65°
A i believe hopefully that is the right answer
