Answer:
34
9 + 25
Step-by-step explanation:
Step 1: Define expression
a² + b²
a = 3
b = 5
Step 2: Substitute
3² + 5²
Step 3: Evaluate
9 + 25
34
Answer:
Step-by-step explanation:
The horizontal distance from points (5,-18) and (8,-17) is 3 because it is 3 units from 5 to 8. The vertical distance is 1 since it is one unit from -18 to -17. Now we can use the equation 
where a=3 and b=1 and c is the distance that you are looking for:
The value of x in the equation is 59/5
<h3>How to solve for x?</h3>
The equation is given as:
5x = 59
Divide both sides by 5
x = 59/5
This means that the value of x in the equation is 59/5
To know if the value is accurate, we simply multiply 5 by 59/5 and we get 59 as in 5x = 59

You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
