If you rotate the triangle so that the 6 is on the bottom, the two sides are both 6.2.
Because the two sides are equal the two angles at the bottom would also be equal. One is given as 61 degrees, so the other bottom angle is also 61 degrees.
The three inside angles of a triangle need to equal 180, so X would equal 180 minus the two bottom angles.
X = 180 - 61 - 61 = 58 degrees.
Answer:
The twins would be 13 years old.
Step-by-step explanation:
21+21+21+13+13 = 89
Answer:
The system of the equations has no solution; the two lines are parallel.
Step-by-step explanation:
The equations have the same slope. In standard form, this can be seen as the same coefficients for x and y. We will multiply the second equation by -12 to reveal this.
![\frac{1}{4} x-\frac{1}{3}y=1 \\-12(\frac{1}{4} x-\frac{1}{3}y=1)\\\frac{-12}{4} x-\frac{-12}{3}y=-12\\-3x+4y=-12](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20x-%5Cfrac%7B1%7D%7B3%7Dy%3D1%20%5C%5C-12%28%5Cfrac%7B1%7D%7B4%7D%20x-%5Cfrac%7B1%7D%7B3%7Dy%3D1%29%5C%5C%5Cfrac%7B-12%7D%7B4%7D%20x-%5Cfrac%7B-12%7D%7B3%7Dy%3D-12%5C%5C-3x%2B4y%3D-12)
This means the equations are parallel and will never cross. There is no solution.
