sum of two angles of triangle are equal to the exterior angle of triangle
5c^5 + 60c^4 + 180c^3
find the GCF, 5c³
5c³(5c^5 + 60c^4 + 180c^3/ 5c^3)
5c³(c² + 12c + 36)
5c³(c² + 2(c)(6) + 6²)
5c³(c + 6)² <<< the answer.
hope this helps, God bless!
Answer:
The answer is A, 50°.
Here, angle CAB= 60°.
In triangle ABC,
60°+70°+ angle ABC= 180°.
angle ABC= 50°.
