Please Help, If U Get It Ill Give You Brainliest!! Find The Area With Explanation!

Answers

Answer 1

Answer:

4ft

Step-by-step explanation:

we will use the formula which states area of triangles is equal to base multiplied height divided by 2

base=5ft

height=8ft

area=5*8/2

=13/2

=6.5ft

this pic is not clear pls mention better next time I was confused what is 4ft and what is 8ft however if I have understood wrong I have also written the formula.

Given:

The figure of a right triangle ABC.

To find:

The trigonometric ratios [tex]\sin B, \tan A, \cos B[/tex].

Solution:

Using Pythagoras theorem,

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex]AB^2=AC^2+BC^2[/tex]

[tex](10)^2=(6)^2+BC^2[/tex]

[tex]100-36=BC^2[/tex]

[tex]64=BC^2[/tex]

Taking square root on both sides.

[tex]\sqrt{64}=BC[/tex]

[tex]8=BC[/tex]

So, measure of BC is 8 units.

Now,

[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]

[tex]\sin B=\dfrac{AC}{AB}[/tex]

[tex]\sin B=\dfrac{6}{10}[/tex]

[tex]\sin B=\dfrac{3}{5}[/tex]

Similarly,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

[tex]\tan A=\dfrac{AC}{BC}[/tex]

[tex]\tan A=\dfrac{6}{8}[/tex]

[tex]\tan A=\dfrac{3}{4}[/tex]

And,

[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos B=\dfrac{BC}{AB}[/tex]

[tex]\cos B=\dfrac{8}{10}[/tex]

[tex]\cos B=\dfrac{4}{5}[/tex]

Therefore, the required trigonometric ration are [tex]\sin B=\dfrac{3}{5}, \tan A=\dfrac{3}{4}, \cos B=\dfrac{4}{5}[/tex].

find surface area of this cone ​

Answers

Answer:

SA = 200π cm²

Step-by-step explanation:

The surface area is calculated as

SA = area of base + area of curved surface

     = πr² + πrs ( r is the radius and s the slant height )

Using Pythagoras' identity in the right triangle to find s

s² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )

s = [tex]\sqrt{289}[/tex] = 17

SA = π × 8² + π × 8 × 17

      = 64π + 136π

      = 200π cm²

Hope this helps x

2x+y=21;y=-2x+21
please hurry I need this straight away​

Answers

Step-by-step explanation:

2x + y = 21

Solving

2x + y = 21

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

2x + y + -1y = 21 + -1y

Combine like terms: y + -1y = 0

2x + 0 = 21 + -1y

2x = 21 + -1y

Divide each side by '2'.

x = 10.5 + -0.5y

Simplifying

x = 10.5 + -0.5y

Suppose the heights of the members of a population follow a normal
distribution. If the mean height of the population is 65 inches and the
standard deviation is 3 inches, 68% of the population will have a height within
which range?
A. 59 inches to 71 inches
B. 53 inches to 77 inches
C. 62 inches to 68 inches
D. 56 inches to 74 inches

Answers

Answer:

C; 62 to 68 inches

Step-by-step explanation:

Here, we want to get the population range that is having a probability of 68%

From the empirical rule, a measure of 1 standard deviation above the mean, with 1 standard deviation below the mean will give a total percentage of 68%

From the question;

1 standard deviation above the mean is 65 + 3 = 68

1 standard deviation below the mean is 65-3 = 62

so the range of the height of the population is 62 to 68 inches
