Answer:15

Step-by-step explanation:The formula for volume of a square pyramid is A^2 * h/3 with A being base side length and h being height, so just plug in 3 for a and 5 for h, getting you (3)^2 * 5/3, then 9* (5/3) then 45/3 then 15

Answer:

C.

Step-by-step explanation:

Hi there!

To answer this, we must set it up as

3x(2x^4-12x^2+7)

Now we just use the distributive property to solve.

this becomes 6x^5-36x^3+21x

I hope this helps!

A. Find the measure of m&lt;1<br> B. Find the measure of m&lt;1 ;m&lt;2; m&lt;3
natita [175]

Answer:

A: m<1 = 79 degrees

B: m<1 = 61 degrees, m<2 = 151 degrees, m<3 = 12 degrees

Step-by-step explanation:

A: An exterior angle is equal to the sum of the two opposite interior angles. 27+52 in this case.

B: The sum of the measures of the interior angles in a triangle is 180 degrees.

Since we know the two angles in the right trinagle are 90 and 29 degrees, we add them and subract the sum from 180 which gives us 61 degrees.

Applying what we know from part A, 61 degrees+90 degrees = m<2.

And, since we know m<2 = 151 degrees, we add that and the 17 degrees to then subtract that sum from 180 to get the measure of angle 3 which is 12 degrees.

Ngth of the third side. If necessary, write in simplest radical form.<br> 5<br> V11

Pythagoras theorem - The length of the third side is 6.71unit

What is Pythagoras theorem ?

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a key relationship in Euclidean geometry between a right triangle's three sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The Pythagoras theorem's equation is as follows:

H² = P² + B²

The triangle's third side will be the following length:

Let x represent the triangle's third side's length.

9² = 6² + x²

81 = 36 + x²

x² = 45

x = 6.708

x = 6.71 units

Hence, the third side of the triangle is 6.71unit
