Since AB is the perpendicular bisector of IK, it separates IK into 2 equal segments. So, the two halves of IK are the same length. (From AB to K, and from AB to I) <span />
Answer:
QM = 7 cm
Step-by-step explanation:
Tangents to a circle from an external point are congruent.
The perimeter (P) is the sum of the sides of the triangle, that is
PL + LQ + QM + MR + RN + NP = 42
6 + LQ + QM + 8 + 8 + 6 = 42
LQ + QM + 28 = 42 ( subtract 28 from both sides )
LQ + QM = 14
Since LQ = QM , then
QM = 7
The measures of the angles in a triangle add up to 180°.
Y + 5 = 3(x + 4)
Because in point-slope format, it is: y-(y-value) = m (x-(x-value)), where m=slope, and the point: (-4,-5) can be written as: (x-value,y-value),
So y - -5 = 3 (x - -4)
