Step-by-step explanation:
Answer:
138
Step-by-step explanation:
5x+2+6x+90=180
11x+92=180
11x=88
x=8
5(8)+2. = 42
180-42= 138

Answer:
<em>B. Triangles A and C</em>
Step-by-step explanation:
Let's find the missing angle of all Triangles:
Triangle A: 180-110-30=40°
Triangle B: 180-30-45=105°
Triangle C: 180-110-40=30°
All triangle angles in numerical order:
ΔA: 30, 40, 110
ΔB: 30, 45, 105
ΔC: 30, 40, 110
We see that only ΔA and ΔC are congruent with the same angle sizes.
