Answer:
cos 25° = X/11
and
sin 65° = X/11
is this good enough or do you need more workings?
Answer:
9x² − 12x + 4
Step-by-step explanation:
A perfect square trinomial:
a² + 2ab +b²= (a + b)²
a² - 2ab +b²= (a - b)²
9x² − 12x + 4 = (3x)² - 2*(3x)*2 + 2² = (3x - 2)²
36b² − 24b + 16
16x² − 24x − 9
4a² − 10a − 25
The equation is (x-4)^2=6(y-1)
Dude that’s the answer....hellloooo
