Question

In Fig. 19.25, two angles are indicated. What the measure of ACX?

Answer 1

hello frnd
here is ur answer...
.
. according to the question
there are 2 angles are 60 and 70 respectively.

Answer 2

In the figure,
Triangle ABC has an exterior angle angle ACX,
m ( Angle BAC ) =60 Degree
m (angle ABC ) = 70 Degree --------{Given }

m (Angle ACX ) =m (Angle BAC ) + m (Angle ABC )
-----{ By Remote Interior Angle test of Triangle }----------
m (Angle ACX ) = 60 Degree + 70 Degree
m ( Angle ACX ) = 130 Degree



Hope it helps you!
