QX=QX(common)
ang.QSX=ang.QTX(90°)
triangleXTQ is congruent to triangleXSQ {By aas}
19)congruent triangleABC and EDC by aas then find the value
similarly sss se dono triangle similar hoga
Answer:
PLS MARK ME AS THE BRAINLIEST FOR THIS......
Step-by-step explanation:
19) part one)
IN TRIANGLE ABC & TRIANGLE EDC,
BC = DC (GIVEN)
ANGLE ACB = ANGLE DEC (VERTICALLY OPPOSITE ANGLES)
ANGLE ABC = ANGLE EDC (ALT. INT. ANGLE)
BY ASA CONGRUENCE RULE
TRIANGLE ABC ≅ TRIANGLE EDC
SO,
AB = ED (BY CPCT)
AC = EC (BY CPCT)
2X-4 = 14
2X = 14 + 4
2X = 18
X = 18/2
X = 9
.
3Y+5 = 20
3Y = 20-5
3Y = 15
Y = 15/3
Y = 5
PART TWO)
PROVE BY CONGRUENCY.. THEN
Y - 6 = 30 (ANGLES OPPOSITE TO EQUAL SIDES ARE EQUAL)
Y = 30 + 6 = 36
.
2X + 7 = 63
2X = 63-7 = 56
X = 56/2
X = 28
