Answer:
the answer would be 13.75 feet
Step-by-step explanation:
The computation of the tall is the building as follows:
Given that
Base is 6 foot
And, the hypotheses is 15 feet
Here we use the Pythagoras theorem
= √15^2 - √6^2
= √225 - √36
= √189
= 13.75 feet
Hence the answer would be 13.75 feet
A number with the value of one added with another number with the value of one will equal two
Answer:
the length of the third side is 12.1m
Step-by-step explanation:
by Pythagoras we know the relationship of the sides of a rectangular triangle that is given by the formula h^2 = l1^2 + l2^2
h = hypotenuse = 14m
l1 = leg1 = 7m
l2 = leg2
h^2 = l1^2 + l2^2
14^2 = 7^2 + l2^2
196 = 49 + l2^2
196 - 49 = l2^2
147 = l2^2
√147 = l2
12.124 = l2
rounding to the nearest tenth
l2 = 12.1
