Answer:
90°, 78°, 12°
Step-by-step explanation:
let the third angle be x then the second angle is 7x - 6
Since 1 of the angles in the triangle is 90° then the second and third angles sum to 90° , then
x + 7x - 6 = 90
8x - 6 = 90 ( add 6 to both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Then
second angle = 7x - 6 = 7(12) - 6 = 84 - 6 = 78°
The 3 angles are 90°, 78°, 12°
Cross multiply
5*27=135
3*x=3x
set equal to one another
3x=135
solve for x
135/3=x
45=x
x=45 minutes
Step-by-step explanation:
you cannot add some simple numbers ? you don't know how to use a calculator ?
to solve this yourself is way shorter than putting this in here.
15 + 22 + 30 = 67
Answer:
N27W
Step-by-step explanation:
Add vectors
w = u+v = <-4,3>+<1,3> = <-3,6>
Cartesian Direction
theta = atan(6,-3) (second quadrant) = 180-63.4 degrees = 116.6 degrees
Bearing = 90-theta = -26.6 degrees from north = N26.6W
The value would be 829.89.
The formula we use is
,
where A is the total amount, p is the principal, r is the rate expressed as a decimal number, n is the number of times per year the interest is compounded, and t is the number of years.
We will use 800 for p; 5.25/100 = 0.0525 for r; 365 for n; and (255/365) for t (since it is not a full year):
