Question 2 is z^5 and I calculated x^6 y^8 for the first so it must be either one of the first 2
Given:
Base of a right triangle = 7 in
Height of a right triangle = a
Hypotenuse = 16 in
To find:
The length of side a.
Solution:
Using Pythagoras theorem:
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.
![7^2+a^2=16^2](https://tex.z-dn.net/?f=7%5E2%2Ba%5E2%3D16%5E2)
![49+a^2=256](https://tex.z-dn.net/?f=49%2Ba%5E2%3D256)
Subtract 49 from both sides.
![49+a^2-49=256-49](https://tex.z-dn.net/?f=49%2Ba%5E2-49%3D256-49)
![a^2=207](https://tex.z-dn.net/?f=a%5E2%3D207)
Taking square root on both sides, we get
a = 14.4
The length of side a is 14.4 in.
Answer:
Sum=720 x=105 degrees Angle H=110 degrees Angle I= 100 degrees Angle K= 135
Step-by-step explanation:
*A hexagons angles add up to 720
*This is a hexagon
*No matter how the hexagon is shaped, it's still going to add up to 720
- Combine all of the angles (known and unknown) into an equation to equal 720
- 140+105+(x+30)+130+(x-5)+(x+5)=720
- remove parentheses
- 140+105+x+30+130+x-5+x+5=720
- Combine like terms and simplify
- 3x+405=720
- subtract 405 from both sides
- 3x=315
- divide by 3 on both sides
- 3x/3=315/3
- x=105
- Angle H = x+5
- Plug in x
- 105+5=110
- Angle H= 110 degrees
- Angle I = x-5
- pug in x
- 105-5=100
- Angle I= 100 degrees
- Angle K= x+30
- plug in x
- 105+30=135
- Angle K= 135 degrees
