Answer: Cos A = 0.96, Tan A = 0.29 and Sin A = 0.28

Step-by-step explanation: The right angled triangle can be solved by applying the trigonometric ratios given a follows;

Sin A = opposite/hypotenuse

Cos A = adjacent/hypotenuse

Tan A = opposite/adjacent

In the triangle ABC, the side AB (25) is the hypotenuse [facing the right angle], the side CB (7) is the opposite [facing the reference angle A°] while the side AC (24) is the adjacent [line between the reference angle and the right angle].

Therefore, using angle A as the reference angle;

(a) Cos A = adjacent/hypotenuse

Cos A = AC/AB

Cos A = 24/25

Cos A = 0.96

(b) Tan A = opposite/adjacent

Tan A= CB/AC

Tan A = 7/24

Tan A = 0.29

Sin A = CB/AB

Sin A = 7/25

Sin A = 0.28

$x^2-9x=10|+20.25\\
x^2-9x+20.25=30.25\\
(x-4.5)^2=30.25\\
x-4.5=5.5 \vee x-4.5=-5.5\\

A floor is made up of 20 triangular tiles, each with sides 40 cm, 24 cm and 32 cm. Find the cost of polishing the floor at the r

pochemuha

Answer:

$15360\,\,rupees$

Step-by-step explanation:

Let sides of the triangle be $a,b,c$

$a=40\,,\,b=24\,,\,c=32$

Semi-perimeter (s) = $\frac{a+b+c}{2}$

$=\frac{40+24+32}{2}\\ =\frac{96}{2}\\=48$

Area of one tile $=\sqrt{s(s-a)(s-b)(s-c)}$

$=\sqrt{48(48-40)(48-24)(48-32)}\\ =\sqrt{48(8)(24)(16)}\\ =\sqrt{147456} \\=384\,\,cm^2$

So,

Area of 20 tiles $=20(384)=7680\,\,cm^2$

Cost of polishing the floor at the rate of 2 rupees per sq.cm = $7680(2)=15360\,\,rupees$

A $500 television is on sale for 20% off. However, you must pay 6% in sales tax. What is the final price of the television after

GrogVix [38]

20% off means you are paying 80% of the original price ( 100% - 20% = 80%)

Multiply the price of the tv by 80% to find the sale price:

500 x 0.80 = 400

Now multiply the sales price by 1 plus the tax rate to find final cost:

400 x 1.06 = 424

Final price including tax is $424
