Answer:
Since m<BCA=m<CAB=55°, it follows that |AB|=|AC|, this means triangle ABC is isosceles.
Step-by-step explanation:
In the diagram AB is parallel to DC.
This means that, by the alternate interior angles theorem?
Also the sum of angles in a triangle should be 180° .
Since m<BCA=m<CAB=55°, it follows that |AB|=|AC|
Hence triangle ABC is isosceles.

2. In this problem, when raising a whole fraction to a power, you must both raise the numerator and denominator to that power.
Answer:
Frank is 56 years old
Millie is 44 years old
Step-by-step explanation:
Since three times Millie's age is 132, you can figure out her age by dividing 132 by 3. Since Frank's age is 12 years older than Millie's, add 12 to 132 divided by 3.
Millie's age equation:
x = 132/3
x = 44 years old
Frank's age equation:
x = (132/3) + 12
x = (44) + 12
x = 56 years old
A right circular cone has a circle as its base.
All answers that have B = l * w cannot be correct as that is the area of a rectangle, not a circle.
The area of a circle is A = pi r^2, so you need B = pi r^2 in the formula.
The only formula that is correct is choice D. V = 1/3 Bh, where B = pi r^2
