I think the correct answer among the choices given is option D. The base of the sail can be calculated using the expression 7 cot 50°. The cotangent function of an angle in a triangle is the adjacent side of the angle divided by the opposite side of the angle. From the given data, this is the best function to use.
Answer:
a = 12
Step-by-step explanation:
as C^2 = A^2 + B^2
by Pythagoras theorem
so
A^2 = C^2 - B^2
= 13^2 - 5^2
= 169- 25
144
as 12^2 is equal to 144
hence side a is equal to 12
Answer:
40
Step-by-step explanation:
if you used cross products you'd pair 8 with 100 and n with 20
That written out would be 8(100)=20n
8(100)=800
800=20n
Divide on both sides
800/20=40
20/20 (cancels out)
Therefore n=40
The mixed number would be 4 1/3, this is because of the 5 trays of brownies, 4 entire ones were sold which means only a fraction of the 5 one was sold. (4 out of 12) 4/12 could be simplified by dividing the top and bottom with 4 which leaves us with 4 1/3
