Answer 1

Answer:

Step-by-step explanation:

1 i )

120 = x + c

112 = x + a

Adding both

x + c + x+ a = 232

=> x + (180) = 232

=> x = 52°

1 ii)

120 = c + x

110 = b + x

=> b + c + x + x = 230

=> 180 + x = 230

=> x = 50°

4 All three angles are equal

x + x + x = 180

=> 3x = 180

=> x = 60°

5. two acute angle equal of a right angle triangle

x + x + 90 = 180

=> 2x + 90

=> x = 45°

6. 100 = x + x

=> x = 50°
