Answer:
Value of blank 1 is 2
Value of blank 2 is 10
Step-by-step explanation:
We are given that a and b are the lengths of legs of right angle in right angled triangle .
b = 3
We are also given that c is the hypotenuse
c = hypotenuse = 7
To find the value of 'a' we will use Pythagoras theorem
A)
89 km
a^2+b^2=c^2
80^2+39^2=c^2
6400+1521=c^2
7921=c^2
sqrt of 7921=89
