Step-by-step explanation:
1) take your protractor and keep in on point R and measure 60° from left side of the protractor and mark the measurement. draw a ray through the measurement and let it intersect the previous ray drawn from point Q , and you will get your point P and the intersection of the two rays.
2) Ab=4cm,Bc=5cm ,M angle =50° ... a ray BX making an angle 50° with AB. step 4 draw an arc of radius 5 cm from B which cuts a ray BX at C.
3) Draw a line segment QR=5.4 cm,then with the help of protector,draw 40° angle at Q,Extend that line up to X. Measure 6.5 cm with compass and draw an arc of 6.5cm on line QX. Join X to R. Draw a perpendicular bisector of line XR.
4) Construct a triangle pqr with angle p =60 degree and q = 30 degree and pq = 4.8 cm . measure angle r .what kin… Get the answers you need, ...
