17x + 16x + 12x =180
45x = 180
x = 4
Largest angle = 17*4 = 68 degrees

Answer: 68^{\circ}

Step-by-step explanation:

Here, the ratio of the all three angles is 17 : 16 : 12

Let the measurements of the angles are, 17 x, 16 x and  12 x

Where x is any positive number.

Since, the sum of all three angles is 180°

Therefore, 17 x + 16 x + 12 x = 180^{\circ}

⇒ 45 x = 180

⇒ x = 4

Thus, the measurement of the largest number = 17 x = 17 × 4 = 68°

What value correctly fills in the blank so that the expressions are equivalent?
Rasek [7]

Answer:

8

Step-by-step explanation:

Notice:

32 = (8 x 4)

72 = (8 x 9)

Hence,

32 + 72

= (8 x 4) + (8 x 9)       (factorize out the 8)

= 8 x (4 + 9)

therefore the musing number is 8

Answer:

178

1900 = 5(x+202)

Step-by-step explanation:

Sasha= 5 times Bess and Jeremy

1900 = 5 (202 + X)

/5             /5

380 = 202 + x

-202     -202

178 = x

The Surface Area of a square pyramid is 3600 ft. The slant height is 80 feet and the base is 20 feet. At most how many 1 foot cu
amm1812

Answer:

10,583 flexible cubes

9915 rigid cubes

Step-by-step explanation:

The equation for the surface area of a square pyramid is area of base plus perimeter of base multiplied by the slant height

Surface area = A + 1/2·p·s

The volume of the pyramid = 1/3×A×h

Where:

A = Area of the base = 20 × 20 = 400 ft²

h = The height of the pyramid = √((slant height)² - ((base side length)/2)²)

h = √(80² - (20/2)²) = 30·√7

The volume of the pyramid = 1/3*400*30·√7 = 4000·√7 ft³ = 10,583.005 ft³

If the cubes are flexible, approximately 10,583 cubes

For rigid cubes we have

Given that the height of the pyramid = 30·√7

The slope of the pyramid = 30·√7/10 = 3·√7

So an increase in height of 1 foot gives a reduction in width of 2/(3·√7)

The bottom can hold 400 cubes

The next layer can hold 19×19 = 361

3rd 361

4th 361

5th 324

6th 324

7th 324

8th 324

9th

Continuing, we get a total of about 9915 rigid cubes in the pyramid.

Instructions: Find the measure of the indicated angle to the nearest degree.
PolarNik [594]

Answer:

15.78°

Step-by-step explanation:

Let the angle be x.

From the x, the known sides are the opposite side, O(13) and the adjacent side, A(46)

Therefore, The trigonometric ratio is the tangent ratio.

tan x = O/A

tan x =13/46

x = 15.78°
