Question

 An exterior angle of a triangle is 145 degrees. If one of its interior opposite angles is 75 degrees, then the two remaining angles are ---------------- degrees​

Answer 1

Step-by-step explanation:

by exterior angle property

opposite interior angles will be equal

so 75 + x equals to 145 degree

x equals to 70 degree

by angle sum property

a+b+c equals to 180 degree

70+75+c equals to 180 degree

c is 105 degree

Answer 2

Answer:

second angle 35°and third angle is 70°

Step-by-step explanation:

exterior angle +Interior angle =180 linear pair

145 + interior angle =180

interior angle =180-145

interior angle =35

75 +35+ third angle =180 Angle Sum Property

110+ third angle =180

third angle =180-110

third angle =70
