Answer:
h = 2
b = 3
Step-by-step 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
