Question

plz solve the both question if you can

Answer 1

for first question both the angle are 45° .Bcoz : since <acb is 90° since it is in semi circle. so sum of all angle of triangle ia 180 and
so:
<acb+<cab+<abc=180
90 + x +x =180
2x = 90
x =45 so both angle is 45
HOPE YOU UNDERSTAND
I M UDAY RATE ME : - )

Answer 2

angle x will be equal to 35° and angle CAB is equal to 45° since angle C is 90° and AC =BC
so using angle sum property angle BAC=45°
