? = 73°

There are 7 sides in this polygon

Calculate total interior angles using (n-2) * 180

["n" denotes number of sides]

Here total interior angle: (7-2)*180 = 900°

The missing angle inside the polygon:

900° - 130° -119° -130° -154° -130° -130°

900° - 793°

107°

A straight line has total 180°

? + 107° = 180°

? = 180° - 107°

? = 73°

URGENT!! DESPERATE!! GEOMETRY REFLECTIONS!!! PLEASE INCLUDE EXPLANATION BOGUS ANSWERS WILL BE REPORTED

serious [3.7K]

When we reflect a point across y=x, the x and y coordinates switch out , that is (x,y) becomes (y,x) . SO for point (1,2), on reflection across y=x, (1,2) becomes (2,1) . And when we do reflection across y=-x, (x,y) becomes (-y,-x). Therefore point (2,1) on reflection across y=-x becomes(-1,-2) .

So the final answer is (-1,-2) .

Find m∠TUL.

pogonyaev

Step-by-step explanation:

Actual graph for this problem is attached below

m∠TUV = 167°

m∠TUL = (x + 11)°

m∠LUV = (11x)°

m∠TUV= m∠TUL+ m∠LUV

now plug in the angles for each
