Answer 1

Answer:

a) 69 degree as sum of the angles opposite to the exterior angle will be equal to the exterior angle which is 121 .... 52degree+a=121

a=69degree

b) 152 degree=a+111 degree

a=152-111

a=41degree

Answer 2

$\LARGE{ \underline{\underline{ \pink{ \bf{ANSWER}}}}}$

a) a = 68°

b) a = 41°

Step-by-step explanation:

a) Here in this question the property used is Exterior Angle Property.

So, exterior angle Property States that

• Exterior Angle = Sum of the interior Opposite Angles

• Here in this question Exterior Angle is 121°.

• Here the interior angles are a, 52°.

• So, 120 = a + 52

• a = 120 - 52

• a = 68°

b) Property Used = Exterior Angle Property

• Exterior Angle = Sum of the interior Opposite Angles

• Here in this question Exterior Angle is 152°

• Here the interior angles are a and 111°

• So, 152 = 111 + a

• a = 152 - 111

• a = 41°
