A wall is 60 feet tall. To avoid tipping over, the ladder must be placed 11 feet from the base of the wall. How tall of a ladder must you have to reach all the way to the top of the 60 foot wall?

Answers

61 feet

I got this by doing the pythagorean theorem, which is a^2+b^2=c^2

Plugging in the values, it is 60^2+11^2=c^2

Once solved, it gives you 61 feet
61 feet is the answer okkkkkkkkk

Answers

Answer:

AC=2.868

Step-by-step explanation:

using pythagoras theorem

take 35 degree as reference angle

hypotenuse =5 , opposite =AC , adjacent=BC

using sin rule

sin 35=opposite/hypotenuse

0.5735=AC/5

0.5735*5=AC

2.8675=AC

2.868=AC

Ac=2.868 sorry if I am wrong

1.45 degrees

2.45 dehrees

3.135 degrees

4.135 degrees

5.45 degrees

6.135 deegres

please give brainliest

Answer:

Step-by-step explanation:

for first fox

let it be x

x + 135 degree = 180 degree (being straight line)

x = 180 - 135

x = 45 degree

therefore figure upper box is 45 degree

for box that is  just below 135 degree

first fox = box just just below 135 degree

45 degree = box just below 135 degree

for box that is just below 45 degree

box that is just below 45 degree = 135 degreee (being vertically opposite angles)

for the box that lies on the left side of the transversal

let the fourth box that les on the left side be x

135 + x = 180 degree (being co interior angle)

x = 180 - 135

x = 45 degree

for the box that lies on the right side of the transversal .Let it be y

45 + y = 180 degree

y = 180 - 45

x = 135 degree

y = last box that lies on the left side of 45 degreeing vetically opposite angles)y

last box = 135 degree

which angles are vertical to each other ?

Answers

Answer:

11 and 9

Step-by-step explanation:

Answer:

<12 and <10

Because they are opppsite to each other. So they are vertically opposite angle (V.O.A).

Answers

angle 12 it means next to or closest so it’s in the same line as 12
Angle twelve would be the angle that is adjacent to angle nine

Which expression has a value of 6?

Answers

Answer:

Option 4

Step-by-step explanation:

The answer is option 4 because whenever a number is enclosed in those two lines that come in the left and right sides it means absolute value and absolute value makes the number positive regardless of the sign that it has, so in this case you have the negative but the absolute value makes it positive since it has the absolute value lines.

Option 4 whenever you see “| |” remember to look for the opposite of what’s in those lines for example:

|-3| the opposite would be positive 3!

Find the radius of the circle.
Circumference = 18.84 yd
a. 3 yd
b. 59.16 yd
c. 6 yd
d. 118.32 yd

what's the answer??​

Answers

Answer:

A. 3yd

Step-by-step explanation:

There are two formulas that can be used for the circumference of a circle:

c = πd and c = 2πr

Since we want to solve for the radius, let's use c = 2πr

The circumference, 'c', is 18.84 inches

Since 'π' is an irrational number, we use its approximation of 3.14

We are trying to solve for 'r', which is the radius

The circumference, 'c', is 18.84 inches

Since 'π' is an irrational number, we use its approximation of 3.14

We are trying to solve for 'r', which is the radius

Plugging in, we get:

18.84 = 2(3.14)r

Since 'π' is an irrational number, we use its approximation of 3.14

Notice there are the same amount of decimal places (two!) in the answer as the combined amount of spaces in the numbers being multiplied!

18.84 = 6.28r

The goal is to isolate and solve for 'r', which is the radius

18.84/6.28 = 3

So we get "3 = r", which means the radius is 3 inches!
