Answer:
The of the pentagon is A=232.48cm²
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, a pentagon
Now given the apothem the area can be expressed as
A=a²n tan (180/n)
where
a = the length of the apothem (in radius)
n = the number of sides= 5 for pentagon
tan is the tangent function calculated in degrees
Substituting our given data we can solve for the area A
A= 8²*5 tan (180/5)
A= 64*5 tan 36
A= 320tan 36
A= 320*0.7265
A=232.48cm²
Answer:
£210
Step-by-step explanation:
Given that :
Visa cost = £2300
7% charge of visa price = (0.07 * £2300) = £161
Total cost = £(161 + 2300) = £2461
Amount to be saved per month = £2461 / 12 = £205.08333
= £210 (nearest £10)
Using the statement and the condition in letter a. The expressions that could represent are:
3j + 5p = 7.60
j + 2p = 2.90
From the equation, we will now equate each other to have the value of j and p, so j = -2p + 2.90:
3(-2p + 2.90) + 5p = 7.60
-6p + 8.70 + 5p = 7.60
-p = -1.10
p= 1.10
j = -2(1.10) +2.90
j = -2.20 + 2.90
j = 0.70
It’s -8 bro dw cause -5 takeaway 3 is -8
