Question

The one who will answer first i will mark him brainlist

Answer 1

Step-by-step explanation:

triangle ACD=35° and triangle ABD=75°

Answer 2

In that triangle AD =DC

that means∆DAC=∆DCA=x

Given∆ADB=70°

then ∆ADC =180°-70°=110° (linear pair)

(Linear Pair means sum of two angles is =180°

that,

Sum of all angles in a triangle=180°

In triangle ACD,

∆ADC+∆DCA+∆DAC=180°

110+x+x=180°

110°+2x=180°.
