Angle ABC= 360 -(133+133) = 94 degrees
Angle BCD = 180 - (22+133) = 25 degrees
Angle ACD = (180-44)/2 = 68
Angle ACB = 68-25 = 43 degrees

For the second part, triangle ABC is isosceles

Answer:

First part

angle ABC=94 degrees

angle BCD=25 degrees

angle ACB=43 degrees

Second part

C) isosceles and obtuse because angle ABC is greater than 90 degrees and angle ACB=angle CAB

Explanation:

All triangles contain 180 degrees.

Triangles ADB and CDB are congruent because side-angle-side theorem.

Since angle ABD=133 degrees, angle CBD=133 degrees because corresponding angles of congruent triangles are equal.

angle ABC=360-133-133=94 degrees

angle BCD=180-133-22=25 degrees

angle ACB=(180-94)/2=43
