Answer:
(8x+13)=(10x-27) being vertically opposite triangles.
Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x
Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x
Answer:
Step-by-step explanation:
Let the number be x
Four time that number = 4x
The difference between a hundred and a number = 100 -x
100- x = 4x
100 = x + 4x
100 = 5x
5x = 100
x = 100/5 = 20
4. Here you would use the Pythagorean Theorem. a² + b² = c²
In this case a and b are the same, so : a² + a² = c² would also work.
a = 5√2 so: (5√2)² + (5√2)² = c²
Do you know where to go from here?
