You are told that the perimeter is 146 units. You look at the diagram and add up all the sides, which tells you the total perimeter. You then equate 146 and the total perimeter, as you know both these equal the perimeter. Then solve for x by using algebra.
Answer:
114°
Step-by-step explanation:
<A=<B (corresponding angles)
6x+12=3x+63
6x-3x=63-12
3x=51
Dividing both sides by 3
x=17
Now
<A=6x+12
=6(17)+12
=102+12
=114°
It would be 12:72. Add all the numbers together to get the second number, and the first number would be 12, or the number of strawberries.
