Answer:
C. 60°
Step-by-step explanation:
To answer this problem we must make use of the sum of the internal angles of a triangle.
For any triangle the sum of its internal angles is equal to 180 °.
So we must add all the angles to find the answer:
now we can add the two terms 'y'
and now we clear for 'y':
The value of y is 60°
Answer:
<h2>A</h2>Step-by-step explanation:
The complete question is
What is the length of leg y of the right triangle?
A right triangle with hypotenuse 26 and legs 24 and y
We need to use the Pythagorean Theorem, where and
,
Therefore, the right answer is A. The length of the missing leg is 10 units.
Let z = sin(x). This means z^2 = (sin(x))^2 = sin^2(x). This allows us to go from the equation you're given to this equation: 7z^2 - 14z + 2 = -5
That turns into 7z^2 - 14z + 7 = 0 after adding 5 to both sides. Use the quadratic formula to solve for z. The only solution is z = 1 (see attached image). Since we made z = sin(x), this means sin(x) = 1. All solutions to this equation will be in the form x = (pi/2) + 2pi*n, which is the radian form of the solution set. If you need the degree form, then it would be x = 90 + 360*n
The 2pi*n (or 360*n) part ensures we get every angle coterminal to pi/2 radians (90 degrees), which captures the entire solution set.
Note: The variable n can be any integer.
