Question

find the unknown angles marked in each of the following figures​

Answer 1

Answer:

50 degree

Step-by-step explanation:

angle BAC=70 degree

angle ACB=60 degree

so in triangle ABC

angle ABC or x = 180-(60+70)=50 degree

Answer 2

Hello mate,

Given:

• Angle ABC = x°

• Angle EAB = 110°

• Angle ACD = 120°

To Find:

• Angle ABC (x°)

$\huge{\star} {\blue{\underline{\huge{</p><p>\textsf{Solution}}}}} \huge{\star}$

Angle BAC = 180 - 110 = 70°

(linear pair)

Angle ACB = 180 - 120 = 60°

(linear pair)

We know that sum of all interior angles of a triangle is equal to 180°

So,

x + BAC + ACB = 180°

x + 70 + 60 = 180°

x = 180 - 130

x = 50°

Hope it helps:)
