Triangle QRS has 3 congruent sides, so it is equilateral and equiangular.
The sum of the measures of the angles of a triangle is 180 deg, so each angle of triangle QRS is 60 deg.
Angle RQS measures 60 degrees and forms a linear pair with angle PQS. Angles in a linear pair a supplementary. That makes the measure of angle PQS 120 deg. leaving only 60 degrees as the sum of the measures of angles PSQ and SPQ. Triangle PQS is isosceles since sides PQ and QS are congruent. The angles opposite congruent sides of a triangle are congruent, so angle PSQ is congruent to angle SPQ. That means angles PSQ and SPQ measure 30 deg each.
m<PSR = m<PSQ + m<QSR = 30 + 60 = 90
m<PQS = 120
m<PSR : m<PQS = 90 : 120 = 3 : 4

Answer:
81000
or 8.1
Step-by-step explanation:
1m = 100cm
10m = 1000cm
a= b*h
a= 1000cm * 810cm
= 810000
1 = 10000
810000 = 8.1
The appropriate response is B. The contend that there is no requirement for understudies to utilize a compass and straightedge, and every single geometric development ought to be finished utilizing a drawing program is the wrong explanation since the power to control drawing programs is just open in a few spots. Not everyone would have the capacity to learn geometry in light of the fact that not everyone can have power. Everyone on the planet would not have a similar opportunity to learn geometry if just drawing programs had the information that we have today.
