In ΔIJK, i = 340 cm, ∠I=120° and ∠J=59°. Find the area of ΔIJK, to the nearest 10th of a square centimeter.

Answers

Answer 1

The area of triangle IJK is 999.8 square centimeters

The given parameters are:

[tex]\angle I = 120^o[/tex]

[tex]\angle J = 59^o[/tex]

[tex]i = 340cm[/tex]

Start by calculating the length of side j using the following sine ratio

[tex]\frac{i}{\sin(I)} = \frac{j}{\sin(J)}[/tex]

Make j the subject of the formula

[tex]j = \sin(J) \times \frac{i}{\sin(I)}[/tex]

Substitute known values

[tex]j = \sin(59) \times \frac{340}{\sin(120)}[/tex]

Evaluate the expression

[tex]j = 337[/tex]

Next, calculate angle K using the following sum of angles formula

[tex]\angle I + \angle J + \angle K =180[/tex]

Substitute known values

[tex]120 + 59 + \angle K =180[/tex]

[tex]179 + \angle K =180[/tex]

Subtract 179 from both sides

[tex]\angle K =1[/tex]

The area of the triangle is:

[tex]Area = \frac{1}{2} ij \times \sin(K)[/tex]

So, we have:

[tex]Area = \frac{1}{2} \times 340 \times 337 \times \sin(1)[/tex]

Evaluate

[tex]Area = 999.8[/tex]

Hence, the area of triangle IJK is 999.8 square centimeters

. Frosty Snacks sells ice cream in a cylindrical cup and in cones.

The small cup of ice cream has a height of 4 inches and a radius

of 2 inches. The small cone has a height of 6 inches and a

diameter of 5 inches. How much more ice cream will fit into a

small cup than a small cone? Use 3.14 for pi.

Answers

Answer:

10.99 in^3

Step-by-step explanation:

Steps to determining the answer

determine the volume of the cylinderdetermine the volume of the conefind the difference in volumes

volume of a cylinder = nr^2h

n = 3.14

r = radius

3.14 x 4 x 2² = 50.24 in³

Volume of a cone 1/3(nr^2h)

n = 22/7

r = radius

A radius is half of the diameter = 5/2 = 2.5 in

h = height  

(1/3) x 3.14 x 2.5² x 6 = 39.25 in³

difference = 50.24  - 39.25 = 10.99 in³

A straight line L is perpendicular to line 3x-2y+4=0. The area of triangle formed by the line L and coordinate axes is 27 sq.unit find equation of line L​

Answers

First write the equation in the standard form of y=mx+c
3x-2y+4=0
3x+4=2y
( divide by 2)
3/2x+2=y
Now let’s find the perpendicular line to y=3/2x+2
You just have to get the opposite of the slope 3/2 which is -2/3
If you multiply 3/2 by -2/3 you will get -1 this proofs it really is the perpendicular slope your are looking for
Hence
The equation of line L is
y=-2/3+2

Answers

Answer:

More sod is needed

Step-by-step explanation:

Well we know that 3/4 of a bag of sod covers 55 ft^2  then  if we divide 55 by 3 we get 18.3333 we take that and multiply by 4 to get 73.333 or the amount one bag of sod can cover

73.333*3 cuz 3 bags of sod is 220 ft^2

Step-by-step explanation:

Since ∠A and ∠B are vertical, we can create the equation: 40 = 5x.

40 = 5x

There is only one other thing we need to do, and that's divide by 5.

40/5 = x

x = 8

The value of x in this case is 8, which is A.

If a cone has a height of 8 inches and a side measurement of 10 inches, what is the radius of its base?

Answers

Answer:

The radius of its base is 6 inches

Step-by-step explanation:

The radius of the base of a cone r , the slant height of the cone l and the height of the cone h forms a right triangle, with the slant height being the hypotenuse of the right triangle

Mathematically, since we have a right triangle, we can find the radius of the base by the use of Pythagoras’ theorem

According to Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides

Thus,

l^2 = r^2 + h^2

l = 10 inches

r = ?

h = 8 inches

10^2 = r^2 + 8^2

100 = r^2 + 64

r^2 = 100-64

r^2 = 36

r = √(36)

r = 6 inches
