Question

in a triangle PQR MN =PR .if QM=4x-3 ,QN=8x-7,PM =3x-1 ,RN=5x-3.find the value of x?​

Answer 1

Answer:

9.7°

Step-by-step explanation:

Angle sum property

∠A + ∠B + ∠C = 180°

Substituting the given value according to formula:

4x - 3 + 8x - 7 + 3x - 1 + 5x - 3 = 180°

20x - 14 = 180°

20x = 180 + 14

20x = 194°

x = 194 / 20

x = 97 / 10

x = 9.7°

X = 9.7°
