Answer:
6√3 = x y =12
Step-by-step explanation:
Since the two sides of the triangles have equal angles then two sides have equal length
the sum of interior angles of triangles is 180° then the last angle is 60°
then the triangles have perfect sides of 12
y = 12
to calculate x
sin Ф = opposite/hypothenus
sin 60° = x/12
sin 60° = √3/2
( √3/2 ) x 12 = x
6√3 = x

.................
90 degrees plus 49 degrees is 139 degrees 180 degrees minus 139 degrees = 41 degrees
90+49=139
180-139= 41
answer 41 degrees
