Step-by-step explanation:
- area of a semicircle=1/2(πr^2
- =1/2×22/7×6^2
- =56.54
X=112
Y=90
Explanation: Y is 90 because you can see that it is a right angle! To find X you can find the 3rd angle that is in the triangle with Y in it (which is 68) and then because X is supplementary to that angle we just found you can do 180-68 which is 112!
