Answer:
θ = 35.39°
Step-by-step explanation:
Given that,
Perpendicular, P = 27
Base, B = 38
We need to find the value of angle. Let the angle be θ. So,
![\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})\\\\\theta=\tan^{-1}(\dfrac{27}{38})\\\\\theta=35.39^{\circ}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7BP%7D%7BB%7D%5C%5C%5C%5C%5Ctheta%3D%5Ctan%5E%7B-1%7D%28%5Cdfrac%7BP%7D%7BB%7D%29%5C%5C%5C%5C%5Ctheta%3D%5Ctan%5E%7B-1%7D%28%5Cdfrac%7B27%7D%7B38%7D%29%5C%5C%5C%5C%5Ctheta%3D35.39%5E%7B%5Ccirc%7D)
So, the required angle is 35.39°.

Given:
Three different integer addition expressions equal −5.
To find:
The three different integer addition expressions.
Solution:
We know that 0 is the identity element under addition. It means if we add 0 to a number we get the same number.
![(-5)+0=-5](https://tex.z-dn.net/?f=%28-5%29%2B0%3D-5)
One expression is
.
The other expression are:
![(-6)+1=-5](https://tex.z-dn.net/?f=%28-6%29%2B1%3D-5)
![(-7)+2=-5](https://tex.z-dn.net/?f=%28-7%29%2B2%3D-5)
Therefore, the three different integer addition expressions that are equal to -5 are
.
