How do I find the indicated value?

Answer:

Step-by-step explanation:

From B on the ground straight up to A and then turn the corner to follow the dotted line...that is a 90 degree angle. So in order to find the angle of depression, subtract 66 from 90 to get 24 degrees. Subsequently, that is also the angle of elevation (the base angle inside the triangle) due to parallel lines and whatnot.

Answer:

9

Step-by-step explanation:

39 x 39 = 1521

1521 divided by 169

= 9    good luck bro

Answer:

b) 12.6 inches

Step-by-step explanation:

tangent is the ratio of the side opposite over adjacent, so if we let x= length of the opposite side, 1.40=x/9, x=12.6 inches

b) 12.6 inches

Answer:

C. No solutions exist Because the situation describes two lines that have the same slope and different y-intercepts

Step-by-step explanation:

it is important to keep the x-and y-coordinates in the same order in both the numerator and the denominator otherwise you will get the wrong slope so there is no solution.

Step-by-step explanation:

A=2πrh+2πr^2

=2×22/7×3×6+2×22/7×3^2

=113.14+56.57

=169.71 m^2

Step-by-step explanation:

r = 3 cm

h = 6 cm

= 2 × 3.14 × 3² + 6 (2 × 3.14 × 3)

= 56.52 + 113.04

= 169.56 cm²

Answer:

261 cm²

Step-by-step explanation:

To find the surface area of a square pyramid, you must first recognize all of the shapes.

There are four triangles and one square.

The triangles have a base of 9 and a height of 10.

[tex]9*10=90[/tex]

Multiply the product by 1/2.

[tex]90*1/2 = 45[/tex]

There are four triangles.

[tex]45*4=180[/tex]

The area of all three triangles is 180 centimeters; the area of a single triangle is 45 centimeters.

There square has sides of 9 centimeters.

[tex]9*9=81[/tex]

The area of the square is 81 centimeters.

Lastly, we add the areas of the shapes.

[tex]45+45+45+45+81 = 261.[/tex]

Therefore, the surface area of this square prism is 261 cm².

You can use this layout to find the surface area of a square pyramid.

If I don't do a good job explaining it then I reccomend you consult the internet

The expression (x + 4)² is not equivalent to the expression 2x² + 8x + 8.

The equivalent is the expression that is in different forms but is equal to the same value.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ (x + 4)²

Simplify the expression, then we have

⇒ (x + 4)²

⇒ (x + 4)(x + 4)

⇒ x² + 8x + 16

Thus, the expression (x + 4)² is not equivalent to the expression 2x² + 8x + 8.

The formula for an area of a kite is:

A=pq/2

--------

p = 20 and q = 25

Multiply the two together (20 × 25)

Then divide by 2 (500 ÷ 2)

Then you get your answer (250)

Whenever you find the area, be sure to add the ² symbol or squared, or else it will be wrong.

Answer:

Step-by-step explanation:

940 divided by 30

try to fit 30 into 94 as many times possible

30*3 =90 , 94 -90 =4

3 goes on top

4 on the bottom and is join by 0 that you bring down to make 40

try to fit 30 into 40

30*1=30, 40 -30 =10

940/30 = 31 remainder 10

Answer:

a) 5units

b) (4.5, 4)

Step-by-step explanation:

Let the coordinate of P and Q be P(3, 2) and Q(6, 6)

PQ can be gotten using the distance formula;

PQ =√(6-2)²+(6-3)²

PQ = √4²+3²

PQ =√16+9

PQ =√25

PQ = 5units

Midpoint M is  expressed as;

M(X, Y) = {(x1+x2)/2, y1+y2/2}

X = x1+x2/2

X = 3+6/2

X= 9/2

X = 4.5

Similarly;

Y = y1+y2/2

Y = 2+6/2

Y = 8/2

Y = 4

Hence the midpoint of PQ is (4.5, 4)

Answer:

1/1560

Step-by-step explanation:

The chance of you winning is 1/40, since there are 40 students and you are one of those students. Since, you cannot win again once you win once, you are eliminated. This leaves us with 39 people left. The chances of your friend being chosen out of the 39 people left is 1/39. Now you must multiply 1/40 and 1/39. After multiplying, you get 1/1560.

Answer:

x =4, x = -6

Step-by-step explanation:

1. Square root the whole equation on both sides

2. You get x+1 = ±5 as the answer.

3. Simplify that to get x = 4 and x = -6.

4. This equation is a quadratic equation, so you should get 2 answers.

Answer:

x=6,−4

Step-by-step explanation:

1.Take the square root of each side of the equation to set up the solution for x

2.Remove the perfect root factor x−1 under the radical to solve for x.

3. Simplify the right side of the equation.
