Question

Delta math need help

Answer 1

Missing side is 2.6

3^2 + x^2 = 4^2

9 + x^2 = 16

-9 -9

x^2 = 7

(
`√(x)`)^2 =
`√(7)`

x = 7

Find the approximation o the square root of 7 in fractions then carry out the long division.

Or

Approx. is 2 3/5 which equals 2 6/10 which equals 2.6

Answer 2

2.6

Explanation:

We'll use the Pythagoras theorem to solve this, which states that in a right angle triangle:

h^2 = a^2 + b^2

4^2 = 3^2 +b^2

16= 9 +b^2

16-9= b^2

7= b^2

(take square root in both sides)

b= 2.65

round to nearest 10th = 2.6
