The data observed from the triangle are given below.

Statement Reason

$\overline{P Q} \cong \overline{P R}$ Given

Draw $\overline{P M}$ so that M is the midpoint of QR. Two points determine a line

$\overline{Q M} \cong \overline{R M}$ Definition of midpoint

$\overline{P M} \cong \overline{P M}$ Reflexive property of congruence

$\triangle P Q M \cong \Delta P R M$ SSS congruence postulate

$\angle \mathrm{Q} \cong \angle \mathrm{R}$ CPCTC

SSS means side-side-side

CPCTC means corresponding parts of the congruence triangle are congruent.

Hence the given triangle is SSS congruence postulate

In a class of 55 21 study physics 24 study geography and 23 study economics and physics. if x students study all three subjects

Rus_ich [418]

The total number of students who studied only two subjects is 13.

The given parameters:

Total number of students, n = 55
Number of physics students = 21
Number of geography students = 24
Number of economics students = 23
Number of students for the 3 subjects, = x
Number of students who studied non = 2x

The number of students who studied only two subjects can be determined by applying overlapping three sets formula as shown below;

$Total = n(phy) + n(geo) + n(econ) + n(none)- n(double) - 2(all \ subjects)\\\\55 = 21 + 24 + 23 + 2x-n(double) - 2(x)\\\\55 = 68- n(double)\\\\n(double) = 68-55\\\\n(double) = 13$

Thus, the total number of students who studied only two subjects is 13.
