Answer:
<em>50° is the correct answer</em>
Step-by-step explanation:
<u>Right Triangles</u>
The right triangles are identified because they have an internal angle of 90°. The basic trigonometric ratios can be used to find angles and side lengths as needed.
We have a right triangle with the following characteristics:
The hypotenuse is 13 units long
The indicated angle is opposite to the leg of 10 units long.
When we know the length of the opposite side, we use the sine ratio. Let's call θ to the required angle:


Using a calculator set in mode <em>degrees</em>, the angle is:


First choice: 52° is not correct because is not a good approximation to 50.3°
Second choice:38° is not correct because is not a good approximation to 50.3°
Third choice: 50° is a good approximation to 50.3°. Correct Answer
Fourth choice: 40° is not correct because is not a good approximation to 50.3°
Answer:
The third one

Answer:
Step-by-step explanation:
To complete the square, divide that 10 in the 10x by 2, then square that answer.
10/2 = 5
5^2 = 25
Add 25 to both sides
By the pythagorean theorem:
h^2=x^2+y^2, h is the diagonal, and x and y are the sides so...
d^2=s^2+(3s)^2
d^2=s^2+9s^2
d^2=10s^2
d=s√10 (since 10=2*5 neither of which is a square so √10 cannot be simplified any further)
The diagonal is s√10 units
