A) Write a as the subject of the formula s=n/2(a+l)? please help .​

AP(Arithmetic progression).

Step-by-step explanation:

Given formula;

s=n/2(a+l)

Explanation;

Given formula;

s=n/2(a+l)

Explanation;

The given formula is used to calculate the sum of the given AP(Arithmetic progression).

In which;

S = Sum of AP(Arithmetic progression).

n = number of terms in AP(Arithmetic progression).

a = first term of AP(Arithmetic progression).

l = last term of AP(Arithmetic progression).

angle q= 92 degree

step-by-step explanation:

the solution is in the picture

when a quadrilateral is inscribed in a circle, the opposite angles are supplement to each other. in other words, the sum of the 2 angle is 180 degree

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
