Abc is a triangle in which points p and r are such that ap equals pr equals rb also points q and s are on ac such that aq equals qs equals sc show that 3pq equals bc?
If M P and Q are collinear and MP plus PQ equals MQ then P is between M and Q.
Assuming that the charhe 'q' is uniformly distributed ina sperical volume of radius Discuss the variation of Electric intensity
Assuming the angles are expressed in degrees: P = 2Q -3° (because "angle P is three less than twice the measure angle Q") P + Q = 180° (because they are supplementary angles) P+Q = 2Q - 3° + Q = 3Q -3° = 180° 3Q = 183° Q = 61° P = 2∙61° -3° = 122° - 3° = 119° If the angles are expressed in radians, the math is similar except you start with P = 2Q - 3 and P+Q = π yielding P = 2π/3 -1 and Q = π/3 +1
Converse: If p r then p q and q rContrapositive: If not p r then not (p q and q r) = If not p r then not p q or not q r Inverse: If not p q and q r then not p r = If not p q or not q r then not p r
