If we join the Center with different corners of the polygon,we find 10 Isoceles triangle with equal side=9.14cm, Making an angle of 36° between the equal sides.
Area of 1 triangle= a*b*sinC/2
= 9.14*9.14*Sin36°/2
= 9.14*9.14*0.587/2
=24.51 cm^2
Area of 10 triangle= 24.51*10
= 245.1cm^2
Answer:
x = we can’t find the value of x because -5x has a variable and 9 doesn’t, so we can’t do anything.
Answer: 16 C 17 B i cant even read it if im right i want the brainliest
Step-by-step explanation:
Answer:
X = 7.24 or 7.2
Step-by-step explanation:
Tan46/1 = x/7
Cross multiply to get this outcome:
7tan(46)
Put into calculator
Then your answer will be X = 7.24 or 7.2
Hope that helps :)
They are all perfect squares because if you took the square root of them you will get a single number. Like the square root of 25 is 5 bc 5(5) is 25
16 is 4 bc 4(4) is 16
9 is 3 bc 3(3) is 9
1 is 1 bc 1(1) is 1
& so on & so forth
