Find the measures of the angles of an isosceles triangle with a vertex angle of 42 degrees
I am Lyosha [343]

Answer:

69°, 69°, and 42°

Step-by-step explanation:

Isosceles triangles have three angles -- one vertex angle and two base angles.

The <u>base angles have the same measure</u> and the vertex angle has a different measure.

<u>Remember all triangles' interior angles sum to 180°.</u>

If the vertex angle is 42°, then the two base angles combined are:

180° - 42° = 138°

Since the base angles are the same, <u>each base angle is:</u>

138° ÷ 2 = 69°

Therefore the angles in the triangle measure 69°, 69°, and 42°.

What is a counterexample to the conditional statement?
posledela

Answer:

The number 9 is greater than 1 and less than 10, while its factors are 1, 3 and 9, therefore it is a counter example to the statement.

Step-by-step explanation:

There are four odd numbers between 1 and 10, they are: 3, 5, 7 and 9. Let's check the factors for each of them.

For 3:

\frac{3}{1} = 3\\\frac{3}{3} = 1

Therefore 3 is not a counter example to the statement, because it behaves as stated.

For 5:

\frac{5}{1} = 5\\\frac{5}{5} = 1

Therefore 5 is not a counter example to the statement, because it behaves as stated.

For 7:

\frac{7}{1} = 7\\\frac{7}{7} = 1

Therefore 7 is not a counter example to the statement, because it behaves as stated.

For 9:

\frac{9}{1} = 9\\\frac{9}{3} = 3\\\frac{9}{9} = 1\\

Therefore 9 is a counter example to the statement, since it can be divided by 1, 3 and 9.
