Answer:
Step-by-step explanation:
You need the Law of Cosines for this, namely:
where x is the missing side.
and
so
x = 18.0 or just 18
Angle A = arctan(12/5) = 67.4 degrees
Angle A = arccos(5/13) = 67.4 degrees
yes the answer was the same
Answer:
y=4x-5.
Step-by-step explanation:
slop-interception form of the required line is y=kx+b, where k - slop, b - intercept;
1) to find value of k:
if the required line is parallel to the given line, then slop of the given line = slop of the required line, it means k=4 and the required line is y=4x+b;
2) to find the value of 'b':
if to substitute the given coordinates into the equation of the given line, then:
15=4*5+b, b= -5.
3) finally, y=4x-5
Answer:
£13.5.
Step-by-step explanation:
Let the share of Brendon, Asha and Julie is 3x, 2x and 6x respectively.
The total amount of money that Asha and Julie recieve is £36
i.e.
2x+6x = 36
8x = 36
x = (36/8)
Amount recieved by Brendon,

So, the amount of money that brendon receives is £13.5.
