For Q 5, fins the points of intersection between the lines, and then just show that either the triangle obeys Pythagroas' Theroem or use trig to show one angle is 90 degrees,

For Q10, the first part is substitution of values, for the second part the nth term of an AP is a+(n-1)d, so 9=a+2d and 33=a+6d, third part use the formula n/2(2a+(n-1)d), for the last part find a and d then use the same formula as for the third bit

Wold tell yo more but I dont think we're allowed to post much more than tips.
