Answer:
x = 4
y = 6
Step-by-step explanation:
Given:
An angle is 45°
The length of the opposite side, hypotenuse and adjacent side of the right triangle is 4, y and x.
Find x, y.
Solution:
In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.
Now we substitute tan(45) = 1 in above equation.
x = 4
The adjacent side of the right triangle is 4.
Now, we use Pythagoras theorem for determine y value.
---------(1)
where c = hypotenuse of triangle.
a = Adjacent side
b = Opposite side
Now, we substitute value of adjacent side and opposite side in equation 1.
y = 6
Therefore, the value x = 4 and y = 6.
Answer:
Step-by-step explanation:
1 ) 2 + 7t [ there are no like terms , so no further simplifying ]
2) 6r + ( - 16 r )
= 6 r - 16 r [ both are like terms ]
= - 10 r
3) (3x + 2 ) + ( 2x - 4 )
= 3x + 2 + 2x - 4
= 3x + 2x - 4 + 2 [ arranging like terms together ]
= 5x - 2
4) (8 n² - 3 n + 6 ) + ( n - 2 )
= 8n² - 3n + 6 + n - 2
= 8n² - 3n + n + 6 - 2 [ bringing like terms together ]
= 8n² - 2n + 4
