Can someone show me the steps to solve the problem?

Hello from MrBillDoesMath!

320 sqrt(3)

Discussion:

Per the attachment,

cos(30 ) = n/ 32 =>  n = 32 cos(30) = 32 (sqrt(3)/2) = 16 sqrt(3)

So

area of shaded triangle =  

area triangle DBC =

area triangle ADC - area triangle ABD =

1/2 (n) * (m + 40)    - 1/2 n * m =

1/2  n*m  + 1/2 (40n) - 1/2 n*m =

1/2(40n) =

20n =

20 ( 16 sqrt(3)) =                                as n = 16 sqrt(3)

320 sqrt(3)

Thank you,

MrB

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

hope i .

answer: f = 32.2m

step-by-step explanation: that is the answer
