Answer:
∠ KAL = 90° (Proved)
Step-by-step explanation:
See the attached diagram.
As KLMN is a parallelogram, so ∠K + ∠ L = 180°
⇒ ............ (1)
Now, given that, and
So, ∠ AKL + ∠ ALK = 90° {From equation (1)}
Now, from Δ KAL, ∠ AKL + ∠ ALK + ∠ KAL = 180°
⇒ 90° + ∠ KAL = 180°
⇒ ∠ KAL = 90° (Proved)
2x+-3y=22 I think. I learned this last year but I don't know
The reflection of point S across the y-axis is point V. The reflection of point Q across the x-axis and the y-axis is point V, whose coordinates are (-5,-5.5).
