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.
Yes 46 and 105 are relatively prime
<span>Sum of Interior Angles = (Number of Sides -2) • 180 degrees
</span>
<span>Number of Sides = (Sum of Interior Angles / 180) +2
</span><span>Number of Sides = (900 / 180) +2
</span>
<span><span>Number of Sides = 7</span>
</span>
It's a heptagon
<span>Round this to the nearest thousand. 4,589,215
= </span>4,589,000
Answer: C
I put the working in the other question you put up, but to put it briefly, multiply everything by 6 because all the options provided have a -6 inside that was meant to be the -1
