Pls help me with this question and pls don't answer if you don't know. thank you,

I apologize if this was poorly explained. The explanation for each is below the angle.

Since these triangles are in a rectangle, The top and bottom triangles are congruent, and the left and right triangles are congruent. All 4 triangles are also Isosceles. (Two equal sides/angles)

m<1= 59

(Left and right triangles are congruent)

m<2=31

(Top and bottom triangles are congruent)

m<3= 59

(Directly across from the other 59)

m<4=31

(Each of the rectangles corner angles totals to 90 degrees, therefore making this angle 31 degrees.)

m<5=31

(Since the triangles are isosceles, this angle is also 31)

m<6= 59

(Since m<5 is 31, this angle is 59.)

m<7=118

{(Two other angles in the triangle) 31+31= 62 180-62= 118)}

m<8=62

{(Two other angles in the triangle)59+59= 118. 180-118= 62}

m<9=62

(This angle and m<8 are congruent.)

m<10=118

(This angle and m<7 are congruent.)

m<11=31

(Same reason as m<4)

I hope this helps!
