Name a pair of overlapping congruent triangles in each diagram. State whether the triangles are congruent by SSS, SAS, ASA, AAS,
MariettaO [177]

Answer:

ΔPTS≅ΔRTA by AAS axiom of congruency

Step-by-step explanation:

Consider ΔPQA and ΔRQS

∠PQA=∠RQS     (Vertically Opposite Angles)

∠QAP=∠QSR     (Complementary of two equal angles, ∠RAT and∠PST)

Due to angle sum property of a triangle, we come to the conclusion that

∠APQ=∠SRQ

Consider ΔPTS and ΔRTA

TA=TS  (Given)

∠RAT=∠PST(Given)

∠APQ=∠SRQ (Proved above)

Therefore, ΔPTS≅ΔRTA by AAS axiom of congruency.

Find the volume of a cone with a base diameter of 12 m and a height of 10 m.
dexar [7]

Answer:

=376.8 m^{3}

Step-by-step explanation:

V=nr^{2}  \frac{h}{3}  Where V is the volume , r is the radius and h is the perpendicular height .

r = \frac{12}{2} m=6

h = 10m

n=3.14

v= 3.14 * 6*6 *\frac{10}{3}

=376.8 m^{3}
