You would need to write a solvable equation, and you can do this because you know that angles in a triangle add up 180° so the missing angle must be (180 - 9x). This makes the equation:
5x + 9 + x + (180 - 9x) = 180
6x + 9 + 180 - 9x = 180
-3x + 189 = 180
- 189
-3x = -9
÷ -3
x = 3
So your answer is x = 3, I hope this helps!
Answer:
√96
Step-by-step explanation:
halve the diameter to set up the pythagorean theorem
2²+b²=10²
4+b²=100
-4 on each side
b²=96
square root each side
b=√96
it could the be further simplified to 4√6
The pythagorean theorem is as follows:
a^2+b^2=c^2
a and b represent the length of the two legs of a triangle while c represents the length of the hypotenuese.
Hope this helped :)
The third one is the correct answer I think
Answer:
B
Step-by-step explanation:
The pattern is to add 4 each time. So 17+4 is 21, 21+4 is 25, and 25+4 is 29
