As <GNJ & < JNK form a striaght angle
And < JNK = 90°
So <GNJ = 90°
So <GNH + <HNJ = 90°
So GNH & HNJ are complimentary is true.
As JNK and KNL do not form a straight angle.
So <JNK +< KNL is not equal to 180°.
Hence JNK and KNL are supplementary is not true.
As <KNM & < JNK form a straight angle
And < JNK = 90°
So <KNM = 90°
So <KNL + <LNM = 90°
So KNL & LNM are complimentary is true.
As HNL makes a straight angle
And so
mHNK + mKNL = 180° is true
As MNG itself is 90°
So
<MNG + <GNH cannot be 90° hence this is false.
(x - a)^2 + (y - b)^2 = r^2 is a circle with centre at (a, b) and radius of r
The correct answer is (x - 2)^2 + (y + 10)^2 = 9 ie the first one
