Answer:

Height of the tree is approx 17.74 feet.

Step-by-step explanation:

the angle of elevation of the sun at 10:00 a.m. is 29°.

Then measure of angle C = 29°

At that point, a tree’s shadow is 32 feet long.

Then BC=32

Now we need to find about how tall is the tree.

So we can use trigonometric formula of right triangle to find missing height (x) of side AB.

\tan\left(C\right)=\frac{AB}{BC}

\tan\left(29^o\right)=\frac{x}{32}

\tan\left(29^o\right)=\frac{x}{32}

0.55431=\frac{x}{32}

0.55431*32=x

17.73792=x

Hence height of the tree is approx 17.74 feet.

A line that includes the points (9,j) and (10,4) has a slope of 1. What is the value of j?
Sergeu [11.5K]

Answer:

soln

A=(9,j)

x1=9,y1=j

B=(10,4)

x2=10,y2=4

slope=1

by using the fomulaof slope,

slope=y2-y1/x2-x1

1 =4-j/10-9

1 = 4-j/1

1=4-j

j=4-1

j=3

After losing 3 baseball cards, Peter gave half of his remaining cards to Bobby. If Peter gave Bobby 9 baseball cards, how many c
seropon [69]
If Bobby claims Peter started with 21 cards, then we'll work this into our equation.

21 - 3 (that he lost) = 18
18 / 2 (the half he gave) = 9

So this means that he did have 21 cards to begin with. Please reply to this with a list of the answers that can/could be checked!

Which ordered pair (p,r) is the solution to the given system of linear equations?
Misha Larkins [42]

Answer:

(p,r) = (1/3, 2/9)

Step-by-step explanation:

Here, we want to solve a system of equations

We can rewrite the second equation by dividing through by 2

So we have;

4p + 3r = 2

and

5p - 3r = 1

Add both equations:

9p = 3

p = 3/9

p = 1/3

Recall ;

5p - 3r = 1

3r = 5p - 1

Substitute the value or p here

3r = 5(1/3)-1

3r = 5/3 - 1

3r = 2/3

r = 2/9

So we have the solution set as;

(p,r) = (1/3 , 2/9)

shape ABCDEF is an irregular hexagon. prove that the sum of the shape is720 degrees. show ur working. (3marks)​
guajiro [1.7K]

Answer:

Here's one way to do it  

Step-by-step explanation:

Divide the hexagon into triangles, for example, as in the diagram below.

The triangles are all inside the hexagon, so the sum of their interior angles is the sum of those of the hexagon.

The sum of the interior angles of a triangle is 180°.

There are four triangles, so

Sum of interior angles = 4 × 180° = 720°
