Heya friend

$\huge{\mathfrak{\red{\underline{\bigstar{ANSWER}}}}}$

AC stands on line on line segment PQ

SO, angle ACQ +angle ACB =180 degree.

100+ACB=180

ACB =180 - 100

ACB =80 degree.

Now,

AB line stands on line segment PQ

SO, angle ABP +angle ABC =180 degree

120 +ABC=180

ABC =180 - 120

ABC =60 degree.

Then,

By angle sum property we know that the sum of interior angle of a triangle is 180 degree.....

IN triangle ABC

ANGLE > A +B +C =180 degree

A+60 +80 =180

A+140 =180

A=180 - 140

A=40 degree....

May this helps you ✌️
