The sail of a boat is in the shape of a right triangle. Which expression shows the length, in meters, of the sail?

yan [13]

Answer:

The answer is 7(tan 50°)

Step-by-step explanation:

So first you need to find which formula you will be using to do this you need to find if you're talking about the hypotenuse, opposite, or adjacent.

The side that measures 7 meters would be the adjacent because its right next to the angle and its not the hypotenuse because its not the largest side

The side which we do not know the length to will be the opposite side because it is opposite from where the angle is.

There are 3 formulas:

sin A = Opposite side/Hypotenuse = BC/AB

cos A = Adjacent side/Hypotenuse = AC/AB

tan A = Opposite side/Adjacent side = BC/AC

There is one formula that has Opposite and Adjacent which is tangent so thats the formula you'll use

Next you plug in the values that you have so your formula will look like this:

Tan 50° = x/7

A will always be where you plug in the angle and then you plug in the information according to what side it is

Every time that x is the numerator you will just multiply both sides by the denominator which gives you:

7(tan 50°)

Which is your answer :))

Fill in the blanks to make an arithmetic sequence

Arlecino [84]

-----------------------------------------
General Equation:
-----------------------------------------
$T_n = a_1 + d(n - 1)$

-----------------------------------------
Find d :
-----------------------------------------
$a_1 = 11, T_7 = 79,$
$T_7 = 11 + d(7 - 1)$
$-79 = 11 + 6d$
$6d = -79 - 11$
$6d = -90$
$d = -15$

-----------------------------------------
Find general equation :
-----------------------------------------
$T_n = 11 + (-15)(n - 1)$
$T_n = 11 -15n + 15$
$T_n = 26 -15n$

-----------------------------------------
Find the sequence :
-----------------------------------------
$T_1 = 26 - 15(1) = 11$
$T_2 = 26 - 15(2) = -4$
$T_3 = 26 - 15(3) = -19$
$T_4 = 26 - 15(4) = -34$
$T_5 = 26 - 15(5) = -49$
$T_6 = 26 - 15(6) = -64$
$T_7 = 26 - 15(7) = -79$

---------------------------------------------------------
Answer: 11, -4, -19, -34, -49, -64, -79
---------------------------------------------------------
