Answer:
a.cm or 7.21cm
b.cm or 13.04cm
c. x= cm or 11.66cm, y=
cm or 13.82cm
Step-by-step explanation:
a. You have to find the length of the other two sides of the triangle using the information already given. The first side is 6cm and the other is 12-9=4cm. Because it's a right-angled triangle you can use pythagoras
b. You can use pythagoras again because it's a right-angle triangle
c. In this question you have to find x and y. We need to find x first using pythagoras
Now that we've found x we can find y using pythagoras but instead of find c, we will find another side
Hope this helps :)
