Question

Produce the side BC of a triangle ABC to the point D. Given that angle ACD = t and the interior angles of the triangle are x, y and z. If, z + t = 180°, which of the following is correct?​

t + y = x

t = x

t = y

t = x + y

Answer 1

Answer:

t=x+y

Step-by-step explanation:

z+t=180

z=180-t

As x,y and z are 3 angles of the triangle

By angle sum property,

x+y+z=180

x+y+180-t=180

x+y=t
