Answer:
Step-by-step explanation:
a triangles angles add up to 180
subtract 102 from 180
180-102
that’s 78
a and b are equal so divide 78 by 2 to get 39
a and b are both 39
Correct option is C. There are 20 ordered pairs.
Given that ordered pairs (x,y)
such that x is even integer where 4≤x≤10 and y is an integer.
where 4<y<10.
Then even integer 4≤x≤10 are four i:e
4,6,8,10
And integer 4<y<10 are five i:e
5,6,7,8,9
Then ordered pair are = 4×5=20
<h3>What are ordered pairs?</h3>
An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.

Adwoa sold x amount of bread during that week, where a is mathematically given as
x = 2700
This is further explained below.
<h3>What is a commission?</h3>
Generally, a payment made to a representative or employee in exchange for the completion of a transaction or the provision of a service, in particular: a predetermined share of the profits made from the whole sum, which is then distributed to the agent in charge of the company.
i) 20% × x = 540
Therefore
x = 540 × 100/20
x = 2700
In conclusion, During that particular week, Adwoa had a total sales volume of x, where x is denoted by the mathematical expression 2700.
