Answer:
b =15
Step-by-step explanation:
The sum of the angles of a triangle is 180
5b+ 4b+ 3b = 180
12b = 180
Divide by 12
12b/12 =180/12
b =15
Yes that is one way. You can also prove that a shape is a square by looking at the angles and each side are congruent to each other
Answer:
$32
Step-by-step explanation:
Since the question says that all the apples were sold for a total of $160, this means that you have to add the additional basket of the friend's to Olivia's. Since Olivia has 4 baskets of apples and her friend has 1, 4+1=5. Since you're trying to find the unit price for 1 basket, you take the total of $160 and divide it by 5 to find how much each basket of apples costed. Since 160/5 is 32, $32 is your answer.
