Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle is 180 degrees.
Use the exterior angles theorem to find y.
The exterior angle y is the sum of the two remote interior angles:
The sum of angles on a straight line is 180 degrees.
The simplified fraction of 49\112 is 7/16. This results from you finding a common number which can divide into 49 and 112 equally. In this case the number is 7. Resulting in the answer 7/16.
Rearrange the equation by writing
x² + x - 90 = 0
x² + x = 90
x² + x + 1/4 = 90 + 1/4
Recall that (a + b)² = a² + 2ab + b². Then
x² + 2 • x/2 + (1/2)² = 361/4
(x + 1/2)² = 361/4
x + 1/2 = ± √(361/4)
x = -1/2 ± 19/2
x = 9 or x = -10
not too sure but I think your answer would be -5
