Answer:
A
Step-by-step explanation:
You multiply the number of hours he worked to the amount he makes and set it equal to the total he made.
All angles of a triangle added together equal 180 degrees
180=(6x-1)+(x+14)+(20) which simplifies to 180=7x+33
next, solve for x by subtracting 33
147=7x
then solve by dividing by 7
21=x
plug x back into your original equations to find the angle measures
A=6(21)-1 A=125 degrees
B=(21)+14 B=35 degrees
Algebraic fractions are the same as normal fractions, but they have algebraic expressions as the numerator/denominator.
For example,

is a normal fraction, but

is an algebraic fraction.
