Answer:
can you please post with pictures?
because I don't know what degrees the angles are, therefore can't help
x+1/x-1 +1 / x+1/x-1 -1= x
10) 51°
11) 152
Step-by-step explanation:
10) 42 + 9 = 51
11) 45(3.5) + 22(-.25) = 157.5 - 5.5 = 152
the figure could be a rhombus because the 2 lines of symmetry bisect the angles
