Well to find the values of the variables, you would have to use the Pythagorean Theorem. The Pythagorean Theorem states that a²+b²=c². A being one side of the triangle, b being the other side, and c being the hypotenuse. The hypotenuse is the slanted and the longest side of a right triangle. So let's find the the total amount of x and y. 5+7=12 Just plug in the numbers into the equation 12²+5²=c² C would equal 13. So we know that x+y=13. If we plug in 7 and 5 into the equation (solving for y) 7²+5²=c², C would equal 8.6. To find x just do 13-8.6 and we get 4.4. So we know that y=8.6 and x=4.4. Hope I helped!
The sum of two terms are:
- t₅, ₃ = 8
- t₁₁, ₂ = 13
- t₁₅,₁₃ = 28.
<h3>What is the sum about?</h3>
The sum of two numbers is one that tells you to find the sum of two or more numbers, and as such, you have to add the numbers altogether.
t₅, ₃ = 5 + 3
= 8
t₁₁, ₂ = 11 + 2
= 13
t₁₅,₁₃ = 15 + 13
= 28.
Hence the correct sum of two terms are:
- t₅, ₃ = 8
- t₁₁, ₂ = 13
- t₁₅,₁₃ = 28.

Answer:
11.43 ft
Step-by-step explanation:
Mean = sum of low tides / total number of low tides
(20.22 ft + 2.64 ft + 20.22 ft + 2.64 ft.) / 4 = 11.43ft
The symbols, you mean? Those are called "parentheses".
Answer:
15π/2 ft
Step-by-step explanation:
Arc length is given by the formula ...
s = rθ . . . . . r = radius; θ = central angle in radians
A 135° arc has a radian measure of (135)(π/180) = 3π/4. The radius of a circle with a 20 ft diameter is (20 ft/2) = 10 ft. So, the arc length is ...
s = (10 ft)(3π/4) = 30π/4 ft = 15π/2 ft
