The two marks on the angles A and C suggest that those angle are the same, and thus the triangle is isosceles.
So, if the measure of angle C is x, the measure of angle A will be x as well.
To solve the exercise, we must use the fact that the sum of the interior angles of any triange is always 180°.
In our case, the measures of the angles are 70, x and x, so the equation is
He used factoring to break it apart
Answer:
3/8.
Step-by-step explanation:
The total number of possibilities is 2^3 = 8.
2 tails and 1 head , the 3 possible outcomes are:
TTH, THT and HTT.
5 folders - $2 each = 10 $
3 note books - $3 each = 9 $
17 book covers minus 12 = 5
5 book covers - $1 each = 5$
10 + 9+5 = 24$
