Answer:
72°
Step-by-step explanation:
The lengths 25 cm and 8 cm are the sides of the rectangle.
See the attached diagram of rectangle ABCD.
Now, let us assume the diagonal AC makes x° angle with the shorter side BC i.e.∠ BCA = x°
So, using trigonometry we can write
⇒ 
degrees ≈ 72 degrees {Rounded to nearest degree} (Answer)
Answer: 13
Step-by-step explanation: If you add 13 to itself 60 times, you will get 780.
1. A relation is a set from x to a set y is called a function if each element of c is related to exactly one element in y. That is,given an element c in c, there is only one element in y that x is related to.
2. You can set up the relation as a table of ordered pairs. Then, text to see if each element in the domain is matched with exactly one element in the range . if so you have a function
3. The domain is the set of all possible x-values which will make the function "work" and will output real y- values .When finding the domain , remember :the denominator (bottom) of a fraction cannot be zero .
4.
(x + 3)^2 + (x + 4)^2
= x^2 + 6x + 9 + x^2 + 8x + 16
= 2x^2 + 14x + 25
= 2(x^2 + 7x) + 25
= 2[(x + 7/2)^2 - 49/4] + 25
= 2(x + 7/2)^2 - 98/4 + 25
= 2(x + 7/2)^2 + 1/2
Its B
