Answer:5
Step-by-step explanation:
Complementary Angles is a pair of any two acute angles that add up to make 90 degrees
90-80 = 10
the angle is 10 degrees
C is the correct answer
AB + CD = BC + DA
<span>Where A, B, C, and D are points on the quad, and AB is the length of the line A to B, etc. </span>
<span>Since you know three sides, you can easily solve for the fourth. </span>
132, to sum up, the Lcm Of 11 and 12 is 132
