Consider a triangle ABC like the one below. Suppose that a = 31, b = 23, and c = 20. (The figure is not drawn to scale.) Solve t
krok68 [10]

The solution to the triangle is A = 92.0, B = 47.9 and C = 40.1

<h3>How to solve the triangle?</h3>

The figure is not given;

However, the question can still be solved without it

The given parameters are:

a = 31, b = 23, and c = 20

Calculate angle A using the following law of cosine

a² = b² + c² - 2bc * cos(A)

So, we have:

31² = 23² + 20² - 2 * 23 * 20 * cos(A)

Evaluate

961 = 929 - 920 * cos(A)

Subtract 929 from both sides

32 =- 920 * cos(A)

Divide both sides by -920

cos(A) = -0.0348

Take the arc cos of both sides

A = 92.0

Calculate angle B using the following law of sine

a/sin(A) = b/sin(B)

So, we have:

31/sin(92) = 23/sin(B)

This gives

31.0189 = 23/sin(B)

Rewrite as:

sin(B) =23/31.0189

Evaluate

sin(B) =0.7415

Take arc sin of both sides

B = 47.9

Calculate angle C using:

C = 180 - 92.0 - 47.9

Evaluate

C = 40.1

Hence, the solution to the triangle is A = 92.0, B = 47.9 and C = 40.1

Estimate the sum by rounding each number to the given place value.
romanna [79]

Answer:

400,000

Step-by-step explanation:

The given sum is 164,215+216,088

We simplify this to get:

164,215+216,088=380,303

The digit at the hundred thousand position is the rightmost 3.

The digit after it is 8.

Since 8≥5 we round up.

We add 1 to 3 to get 4 and replace all digits to the right with zeros.

We round to the nearest hundred thousand to get:

400,000

If two pyramids are similar and the ratio between the lengths of their edges is
SVEN [57.7K]

Answer:

D. 27:1331

Step-by-step explanation:

The volume ratio for the two solids is the side length ratio raised to the third power.

3 to the 3rd power = 27

11 to the 3rd power = 1331

Find the slope of the line that goes through the<br> (2,6) and (-1, -6)
emmasim [6.3K]
We can use the formula y2-y1/x2-x1 to get our slope. y2 and x2 are our second y and x coordinates, meanwhile y1 and x1 are our first y and x coordinates. -6-6/-1 -2 is -12/-3. -12/-3 is 4, the slope is 4.

What is the distance from the point (0,-4) to point (4,4)?
dlinn [17]

Answer: Distance is 8.9

Step-by-step explanation:

d = √((x2-x1)2 + (y2-y1)2)

(x2-x1) = (4 - 0) = 4

(y2-y1) = (4 -4) = 8

Add it all together

(4)2 + (8)2 = 16 + 64 = 80

Square 80

\sqrt{80} =4\sqrt{5} \\=8.9443
