Answer:
h = 2

b = 3
Explanation:
to find 'h' we can use the ratio of sides in a 30-60-90° triangle which, respectively, is 1 :
: 2
so we can set up this proportion:
h/2 = 1/

cross-multiply:
h = 2

to find 'b' we can use the ratio of sides in a 45-45-90° triangle which, respectively, is 1 : 1 :

we can set up this proportion:
3/b = 1/

cross-multiply:
b = 3
