Find the unknown side of the triangle and explain!!!
klasskru [66]

Since this is a right triangle, we can use Pythagorean theorem. Pythagorean theorem is a^2 + b^2 = c^2

a = one leg of the triangle

b = the second leg of the triangle

c = the hypotenuse of the triangle

in this problem,

a = 8 in

b = 6 in

c = ?

We need to plug our numbers into the pythagorean theorem and solve for c

8^2 + 6^2 = c^2.

Square each term on the left side.

64 + 36 = c^2

Add the terms together on the left side.

100 = c^2.

Take the square root of each side

10 = c

The missing side is 10 inches

What is the recursive formula when given the explicit formula for the following geometric sequence?
GenaCL600 [577]

Answer:

\left \{ {{a_1=12} \atop{a_n=a_{n-1}*(33)}} \right.

Step-by-step explanation:

For a geometric sequence the explicit formula has the following formula:

a_n=a_1(r)^{n-1}

Where a_1 is the first term in the sequence, and r is the common ratio  and a_n is the nth term of the sequence:

In this case we have the following sequence

a_n = 12(33)^{n-1}

Then:

a_1=12\\r=33

The recursive formula for the geometric sequence has the following formula

\left \{ {{a_1} \atop {a_n=a_1*r}} \right.

Where a_1 is the first term in the sequence, and r is the common ratio  and a_n is the nth term of the sequence:

In this case the recursive formula is:

\left \{ {{a_1=12} \atop{a_n=a_{n-1}*(33)}} \right.

A 15-foot flagpole leans slightly, such that it makes an 80° angle with the ground. The shadow of the flagpole is 10 feet long w
Naya [18.7K]

Answer:   48°

<u>Step-by-step explanation:</u>

The shadow is the adjacent side and the length of the flag is the hypotenuse

cos\ \theta=\dfrac{adjacent}{hypotenuse}\\\\\\cos\ \theta=\dfrac{10}{15}\\\\\\cos^{-1}(cos\ \theta)=cos^{-1}\bigg(\dfrac{10}{15}\bigg)\\\\\\.\qquad \qquad \boxed{\theta=48^o}
