A B and D
A & D are known as irregular polygons
The prime factores are 7,2,2,2
The answer is <span>7 x 3/4 in simplest form = 21/4</span>
To find x just set this = to 180 bc is a supp angle so 58+x=180 and then subtract 58 from both sides 180-58=122 rewrite x=122
Hope this helps have a nice day!
The time spent by the repairman there will be 3 hours so the correct answer is option D.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:-
A roof repairman charges a $60 consult fee, and then $45 per hour to complete repairs. if the homeowner pays a total of $195.
The time will be calculated as:-
Total amount = $195
Now the fixed consulting cost will be $60 and will be deducted from the
total amount.
Variable cost = 195 - 60 = 135
The $45 per hour charge so for $145 the time will be:-
Time = 135 / 45
Time = 3 Hours
Therefore the time spent by the repairman there will be 3 hours so the correct answer is option D.
