Question

given that DAV is a straight line find the value of the unknown ​

Answer 1

Answer:

in triangle CDA by angle sum property of a triangle 50+90+b=180 b=180-140=40 degrees b=40 degrees similarly in triangle CAB 35+90+c=180 c=180-125=55 degrees. Hope it helps please mark my answer the brainliest and follow me.

Answer 2

Answer:

in triangle DAC

angle D=50 degree

angle CAD =90 degree

angle DCA=b

angle D+angle CAD + angle DCA=180

50+90+b=180

140+b=180

b=40 degree

similarly, in triangle ABC

35+90+c=180

125+c=180

c=55 degree
