Step-by-step explanation:
Given: A triangle
To prove:
Solution:
Trigonometry is a branch of mathematics that explains relationship between sides and angles of the triangle.
Sine of angle = side opposite to the angle / hypotenuse
In ΔADB,
In ΔBDC,
From equations (i) and (ii),
Hence proved
Answer:
B would be the answer.
Step-by-step explanation:
Use what they said. All angles in a triangle would sum to 180 degrees.
So based on that, 107 + 33 + <x = 180
140 + <x = 180
<x would then be 40 degrees
Answer: The ordered pair is (2,3)
Step-by-step explanation:
To solve this problem, we can use substitution. With substitution, we substitute the y in each problem with the equations. In this case, x + 1 can substitute the y in y = -x + 5. Here is what the problem looks like now:
x + 1 = -x + 5
The reason we used substitution is because we assume that these linear equations are equal. We must prove it, though. We can use algebra.
Move the variables to one side and the numerical values to another:
x + x = 5 - 1.
Simplify.
2x = 4
Simplify.
x = 2.
Now, we got our x value, we can substitute it into our problem:
y = 2 + 1
y + -2 + 5
2 + 1 = - 2 + 5 = 3
Our x is 2, and our y is 3. The ordered pair that is a solution is (2,3).
The triangle has moved 2 to the right and 1 down thus;
2,-1
Hope this helps! :)
