Answer:
h= 4.6, c=7.1
Step-by-step explanation:
First you need to know in a 30 60 90 triangle the sides ratios are x, 2x and x√3, and for 45 90 45 it is x, x and x√2
so <em>h</em> is 8/√3 and you rationalize the bottom so it becomes 8√3/3. when you solve this and round to nearest hundred it becomes 4.6. for the second one, it is 5√2 and when you solve this and round, it becomes 7.1

Answer:
the total distance is 56 cm
Step-by-step explanation:
Given that the area of the bulletin board is 196 cm^2
Based on this, the total distance around the bulletin board is
But before that we need to find out the side
As the area of square is
= side^2
196 = side^2
So side = 14
Now there are four sides, so the total distance is
= 4 × 14
= 56 cm
Hence, the total distance is 56 cm
