Answer 1

hi buddy!!

Solution:

here,

angle C is a right angle.....( angle inscribing a semicircle)

now,

let angle A be x and angle B be y

accordingly,

y= x-10........ (1)

hence,

sum of measures of all angles in a triangle= 180°

hence,

x+y+ 90= 180......(2)

x+ x-10+90= 180

2x+80=180

2x=180-80

2x=100

x=100/2=50

therefore angle A = 50°

now,

substituting value of A in (1),

y= x-10

y= 50-10

y= 40°

Checking:

x+y+90= 180

50+40+90=180

90+90=180

180°=180°

hope this helps!!✌❤☺
