Answer:
y = x + 6
Step-by-step explanation:
Answer:
2(x-3)(x+2)
Step-by-step explanation:
2x^2 - 2x - 12
2(x^2 - x -6)
2(x^2 - 3x + 2x - 6)
2(x(x - 3) + 2(x - 3))
2(x-3)(x+2)
Its a right angled triangle. You have C and have B all you need to find is A. usually for a question like this you would use the Pythagorean theorem which is A2+B2=C2 but since we already have c we will use C2-B2=A2
Now we fill in the values. (21)2-(9)2=A2
441-81=360^2 so now with the 360^2 we have to squareroot it so the square root of 360 is 18.973f
Answer:
14.4
Step-by-step explanation:
We solve the above question using Cosine Rule
The formula is given as:
BC² = AB²+ AC²﹣2 × AB × AC cos A
BC² = 6² + 13²﹣2 × 6 × 13 × cos(91°)
BC = √6² + 13²﹣2 × 6 × 13 × cos(91°)
BC = 14.41258
Approximately
BC = 14.4
