Answer 1

Answer:

• 77°

Step-by-step explanation:

Here,

∠PAC = ∠ACS = 127° [Alternate interior angles]

Where,

=> ∠PAC = 50° + ∠BAC

Then,

=> 50° + ∠ABC = 127°

=> ∠ABC = 127° - 50°

=> ∠ABC = 77°

Answer 2

given★

• in the figure 0.1 in photo PO||RS

• angle ACS =127° and

• angle PAB=50°----(1)

find★

• angle BAC

Solution★

• $\red{PQ||RS}$
• and his transversal $\red{AC}$

• to angle PAC=angle ACS=127°---(2)
• (alternate angle property)

• see figure we get angle PAC=angle PAB+angle BAC --------(3)

• EQ 1 and 2 value put on EQ 3 to we get

• 127=50+angle BAC

• angle BAC=127-50

• angle BAC=77°

============================

finally we get★

$\angle\pink{BAC=77°}$
