The third angle is approximately 75 degrees.
X+12=20 is 8.
x-9=17 and 2x=16 both have the same solution.
The answer should be X+12=20.
Quadrilateral LMNO is a rhombus ( the diagonals bisect each other ).
The system:
y = 3 x
y + 12 = 6 x
3 x + 12 = 6 x
6 x - 3 x = 12
3 x = 12
x = 12 : 4
x = 4
y = 3 * 4
y = 12
Answer: C ) 12
Answer and Step-by-step explanation:
The ratios can be used to find the measures of acute angles in a right triangle when you know the measures of the two sides of the triangle. You must determine which ratio to use depending on which sides are given. Then, use the inverse trigonometric functions on your calculator to find the angle.
