Answer:
D
Step-by-step explanation:
Since the triangle has 2 congruent sides then the triangle is isosceles and the base angles are congruent, thus
x = [tex]\frac{180-50}{2}[/tex] = [tex]\frac{130}{2}[/tex] = 65 → D
Answer:
x = 65
Step-by-step explanation:
This is an isosceles triangle which means that 2 angles are the same and all the angles have to equal 180.
A - 60+60+50 = 170(not 180)
50+50+60 = 160(not 180)
A is eliminated.
B is eliminated because then it will be an equilateral triangle.
C - 130+130+50 = 310(not 180)
50+50+130 = 230(not 180)
C is eliminated which leaves D.
D = 65+65+50 = 180(TRIANGLE!!!!!!!!!!)
