Answer:
9² = 40² + 41² - 2(40)(41) cos(C)
81 = 1600 + 1681 - 3280 cos(C)
81 = 3281 - 3280 cos(C)
-3200 = -3280 cos(C)
cos(C) = 3200 / 3280
cos(C) = 40 / 41
Step-by-step explanation:
Answer:
6 feets
Step-by-step explanation:
The triangle described in the question has been sketched in the picture attached below :
From the triangle, we could solve for X, which is the base of the triangle using trigonometry :
Sinθ = opposite / hypotenus
Sin 30° = x / 12
0.5 = x / 12
x = 12 * 0.5
x = 6 feets
Hence base, x = 6 feets
The answer is C. plug 3 and 4 into the equation and see if it's true.

do u have like a photo or sum to explain it better
Answer:
Answer is below
Step-by-step explanation:
Idk if it 430 or 436 but if it is 436.051 that goes first
then 435.786
435.100
if it is 430.051 then it is in the order of
435.781
435.100
430.051
