Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, scalene, equilateral, acute, obtuse and right angled triangle. A right angle triangle is a triangle with one angle being 90°.
Trigonometric ratios is used to show the relationship between the angles and sides of a right angled triangle. Examples are:
sinΘ = opposite/hypotenuse; cosΘ = adjacent/hypotenuse; tanΘ = opposite/adjacent
From the question:
cos(62) = AB/12
AB = 12 * cos(62)
AB = 5.6 cm
Hi there :-)
Use the formula of the present value of annuity ordinary
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value?
PMT 3250
R interest rate 0.041
K compounded monthly 12
N time 30 years
Pv=3,250×((1−(1+0.041÷12)^(−12×30))÷(0.041÷12))=672,601.61
Hope it helps
y: original price (in dollars)
0.12y: amount of discount (in dollars)
sale price: y - 0.12y = 0.88y
sales tax on this sale price: (0.06)(0.88y)
final cost: 0.88y + (0.06)(0.88y) = 0.88y(1+0.06) = 0.9328y
Answer:
16
Step-by-step explanation:
We can find x using tan 40° which can be represented as x/20. tan 40° is also equal to about 0.8 so that means x / 20 = 0.8 and x = 16.
