A right triangle has one angle that measures 6 degrees. What is the measure of the other acute angle?

Mathematics

84

Step-by-step explanation:

All three angles add up to 180 degrees.

Since it is a right triangle, there is a 90 degrees angle. And we know another angle is 6 degree. So we use the formula: 180 - (known angle + known angle) = unknown angle

Plugging in the information we get: 180 - (90 + 6) = x

180 - 96 = 84

So x = 84

We can check our work by adding all known angles to see if it is equal to 180 using the formula known angle + known angle + known angle = 180 degrees

Plugging in the information we get: 90 + 6 + 84 = 180

96 + 84 = 180

180 = 180

So the answer 84 is correct

Find the first four terms of the sequence given by the formula:
sattari [20]
<h3>Answer: Choice D. 2, 6, 12, 20</h3>

=============================================

Work Shown:

Plug in n = 1

c(n) = n(n+1)

c(1) = 1(1+1)

c(1) = 1(2)

c(1) = 2

The first term is 2

-------------

Plug in n = 2

c(n) = n(n+1)

c(2) = 2(2+1)

c(2) = 2(3)

c(2) = 6

The second term is 6

-------------

Plug in n = 3

c(n) = n(n+1)

c(3) = 3(3+1)

c(3) = 3(4)

c(3) = 12

The third term is 12

-------------

Plug in n = 4

c(n) = n(n+1)

c(4) = 4(4+1)

c(4) = 4(5)

c(4) = 20

The fourth term is 20

-------------

The first four terms are: 2, 6, 12, 20

What is the surface area of the triangular prism?​
AlladinOne [14]

Answer:

<h3>The surface area of the prism is A prism=204m2</h3>

Step-by-step explanation:

Area is the space that is contained in a two-dimensional figure.

Surface area is the total area of all of the sides and faces of a three-dimensional figure.  

To find the surface area, the area of each face is calculated and then add these areas together.

To find the area of a rectangle, multiply the length by the width .

From the graph the length of the rectangle is 10 m and the width is 8 m. Therefore, the area of the bottom face is

From the graph the length of the rectangle is 10 m and the width is 5 m. Therefore, the area of one of the rectangular side faces is

To find the area of a triangle use the following formula  where b is the base and h is the height.

From the graph the base of the triangle is 8 m and the height is 3 m. Therefore, the area of one of the triangular faces is

The surface area of the prism is the sum of the area of the bottom face, the area of the two rectangular side faces, and the area of the two triangular faces
