The three integers are 5,17 and -10
Step-by-step explanation:
Let x, y and z be three integers then
'The sum of the first and second integers exceeds the third by 32'
The third integer is 15 less than the first.
From Eqn 2:
Subtracting Eqn 1 from eqn 2
Dividing both sides by -2
Putting z=-10 in Eqn 3
Putting x=5 and z=-10 in Eqn 1
Hence,
The three integers are 5,17 and -10

Answer:
AB ≈ 6.53
Step-by-step explanation:
using the cosine ratio in the right triangle
cos40° = =
=
( multiply both sides by AB )
AB × cos40° = 5 ( divide both sides by cos40° )
AB = ≈ 6.53 ( to the nearest hundredth )
