Find side lengths b and h

Step-by-step explanation:

1st triangle:

You have two angles of 45degrees, so we have

d^2+d^2=6^2

2d^2=36

d^2=18

d=3\sqrt{2}

2nd triangle:

The opposite line of angle 30 is 4, then opposite line of angle 90 is 2*4=8.

h^2=8^2-4^2=64-16=48

h=4\sqrt{3}

neither i nor ii 56 / 4.9 = 11.91489362 and 82 / (11+5) =5.125 so i is wrong

ii. (24/8+2) times 3 = 15 and (42+9)/2 =25.5
