A whole circle is 360 degrees. So add up the known degrees (115+105+60)=280degrees
Then 360-280=80 degrees
3x-3+4x^2-6x
4x^2-6x+3x-3 (arrange them in order)
4x^2-3x-3
do u want more simplified form ?
The permimiter of a is 18 and the area is 9
Answer:
X = 25
Step-by-step explanation:
We can calculate the value of x using Euclidean theorem
15^2 = 9 × x
225 = 9x divide both sides by 9
25 = x
