Answer: The answer is (B) 58 + 360n, for any integer 'n'.

Step-by-step explanation: We are given to select the correct expression that represents the measures of all angles co-terminal with an angle of measurement 418°.

Co-terminal Angles are angles who share the same initial side and terminal sides.

We can find co-terminal angles by simply as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians.

Therefore, if 'n' is an integer, then all the co-terminal angles with 418° angle is given by

C_a=(418-360)+360\times n=58+360n.

Thus, the correct option is (B).

3. Janet is flying a kite on a string that is 75m long. The kite is 62m above the ground. Estimate the distance between Janet an
konstantin123 [22]
Answer: a) It will be a right triangle with a hypotenuse of 75 and a vertical leg that is 62. 
b) The length of the kite string is 75 (given in the problem). However, I believe you are looking for the distance from the spot on the ground beneath the kite to Janet. That is about 42.2 m.

To find the missing distance in the right triangle. You have to use the Pythagorean Theorem.  I set it up and solve it below.

a^2 + b^2 = c^2
x^2 + 62^2 = 75^2
x^2 + 3844 = 5625
x^2 = 1781
x = 42.2 (about)

What is the value of x?
tensa zangetsu [6.8K]

Answer:

X = 5°

Step-by-step explanation:

180° on a straight line.

180 - 100 = 80 angle ABC = 80°

angle ACB is vertically opposite to the 60° given

ACB = 60°

180 - 80 - 60 = 7x+5

40 = 7x + 5

7x = 35

X = 5

makvit [3.9K]

Answer:

59

Step-by-step explanation:

Let c and b represent the scores of Colin and Brian respectively.  Then

c + b = 59.  Since brian scored 59 more points than Colin, that means c = 0 and b = 59.  Their combined score is 0 + 59 = 59.

A heavy rope, 30 ft long, weighs 0.4 lb/ft and hangs over the edge of a building 80 ft high. Approximate the required work by a
gizmo_the_mogwai [7]

Answer:

180 fb*lb

45 ft*lb

Step-by-step explanation:

We have that the work is equal to:

W = F * d

but when the force is constant and in this case, it is changing.

 therefore it would be:

W = \int\limits^b_ a {F(x)} \, dx

Where a = 0 and b = 30.

F (x) = 0.4 * x

Therefore, we replace and we would be left with:

W = \int\limits^b_a {0.4*x} \, dx

We integrate and we have:

W = 0.4 / 2 * x ^ 2

W = 0.2 * (x ^ 2) from 0 to 30, we replace:

W = 0.2 * (30 ^ 2) - 0.2 * (0 ^ 2)

W = 180 ft * lb

Now in the second part it is the same, but the integral would be from 0 to 15.

we replace:

W = 0.2 * (15 ^ 2) - 0.2 * (0 ^ 2)

W = 45 ft * lb
