A co-terminal angle is basically any radian value that you can get by either adding or subtracting a full rotation from the original one.

In this case, you can do 2pi/7 + 2pi, or 2pi/7 - 2pi.

Your answer is either 16pi/7 or -12pi/7. There’s actually an infinite amount of answers you could get, but these two are the easiest to come by.

Answer:

Question 4: -11

Question 5: -7

Step-by-step explanation:

Four

Every triangle has 180 degrees.

So all three angles add to 180

Equation

60 + 80 + x + 51 = 180

Solution

Combine the like terms on the left. This is the first time I've seen x be a negative value. Almost all of the time it isn't, which should make you wonder.

191 + x = 180

Subtract 191 from both sides.

191 - 191 + x = 180 - 191

x = - 11

Five

If a triangle is a right triangle and one of the angles is 45, then so is the other one.

Proof

a + 45 + 90 = 180 Combine like terms on the left

a + 135 = 180 Subtract 135 on both sides.

a + 135-135=180-135 Combine the like terms

a = 45

Statement

That means 52 + x = 45 and here is another negative answer. Subtract 52 from both sides

52 - 52 + x = 45 - 52 Combine like terms.

x = - 7

Find the correct values for the variables that make the statement cos(h)=x/y true.

Stels [109]

Answer:

The sum of the measures of the angles in a triangle is equal to 180 degree.

In triangle FGH;

$\angle F + \angle G + \angle H = 180^{\circ}$

$\angle H = 180^{\circ} -{\angle F + \angle G}$

Substitute the given values from the given figure we have;

$\angle H = 180^{\circ} -{33^{\circ} + 90^{\circ}}$

$\angle H = 180^{\circ} -{123^{\circ}}$

Simplify:

$\angle H = 57^{\circ}$

Given that:

$\cos H = \frac{x}{y}$

Using Cosine ratio:

$\cos \theta = \frac{\text{Base}}{\text{Hypotenuse}}$

In a given figure:

Base = GH = x and Hypotenuse = FH = y = 80 cm

Then;

$\cos 57^{\circ}= \frac{x}{80}$

$x = \cos 57^{\circ} \cdot 80$

$x = 0.54463903501 \cdot 80 \approx 43.57$ cm

Therefore, the value of :

$H = 57^{\circ}$

x = 43.57 cm

y = 80 cm

What is the area of the composite figure below?

musickatia [10]

Answer:

33 sq cm.

Step-by-step explanation:

Let's calculate each shape serperately,

--------

For the square, the area is 25 since

5 × 5 = 25

-------

For the rectangle, the area is 8:

4 × 2 = 8

-----

Add these together to get 33 sq cm

Have a good day :)
