Answer:
18
Step-by-step explanation:
Look at all factors of 9 that are even; 18, 36, 54, 72, 90
Next divide 198 by those numbers and the only whole number is from 18.
9 x 2 = 18
198/18 = 11
Answer:
1: yes, because side MQ creates two right triangles inside the equalateral one, serving as the leg of both (reflexive property). In each right triangle, MQ would be the height.
2. (im unsure but i THINK i did it right)
1=yes
2=no
3=yes
3:The missing side would be 24.7
Step-by-step explanation:
Explanation for #3- A squared +B sqaured = C squared.
You know that one of the legs is 8 less than 42
42-8=34
34=one of the legs.
lets plug them all in: 42 squared - 34 sqaured = ?
1764-1156= 608
the square root of 608 is 24.7
so the missing side is 24.7
I hope this helps :)
Answer:
13
Step-by-step explanation:
5 12 and 13 are a known triangle proportion relation.
also, 5 squared plus 12 squared is 169.
13 squared is 169.
(I just used the Pythagorean formula)

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
