Question

What does x equal????​

Answer 1

Let angel C be a

now,

a+68°+37° = 180° ( sum of triangles)

or, a+ 105°=180°

or, a= 180°-105°

so, a= 75°

again,

a = x = 75° ( being alternate angle )

so, the required value of x is 75°

Answer 2

x=143°-∠E

Explanation:

In triangle, ABC

37°+68°+∠C=180°..........Sum of all the angles of a triangle is 180°

105°+∠C=180°

∠C=180°-105°

∠C=75°

As,

∠EAD=∠CAB=37°

x+37°+∠E=180°

x=180°-(37°+∠E)

x=180°-37°-∠E

x=143°-∠E
