Question

in the given figure find angle BAC​

Answer 1

Answer:

77 degrees

Step-by-step explanation:

PQ parallel to RS.

therefore, angle BAP = ABC=50 degrees. (alternate angles)

angle ACB + ACS = 180 degrees. (supplementary angles)

therefore, ACB = 180 - 127 = 53 Degrees.

Using interior angles of a triangle =180 property,

BAC + ABC + ACB = 180

therefore BAC = 180 -ABC-ACB

BAC = 180-53-50 = 77 DEGREES
