You need to use the Law of Cosines:
AC² = AB² + BC² - 2·AB·BC·cos(b)
Therefore, you get:
AC = √(90² + 80² - 2·90·80·cos(50)
=√5243.86
= 72.4 in
Now you can sum up all the sides in order to find the perimeter:
AB + BC + AC = 90 + 80 + 72.4 = 242.4 in
The correct answer is A) 242.4 in
0.43 is the answer to your question

f) 3.50 +0.15p ≤ 5.00 . . . . . p is the number of pencils Miranda buys
Answer:
P=0.833
Step-by-step explanation:
The die is six sided so (1,2,3,4,5,6)
Even numbers (2,4,6) P(even)=3/6
Less than 5 (1,2,3,4) P(<5)=4/6
A ∩ B= (2,4) P(A ∩ B)=2/6
The formula to calculate the “or” probability of two events A and B is this: P(even)+P(<5)-P(A ∩ B)
3/6+4/6-2/6=5/6
