Answer: 102°
Step-by-step explanation:
First and foremost, we should note that an isosceles triangle has two sides that are equal and that the sum of angles in a triangle equals to 180°.
Since we are told that the isosceles triangle has base angles that each measure 39°, the third angle will be:
t + 39° + 39° = 180°
t + 78° = 180°
t = 180° - 78°
t = 102°
The third angle is 102°.
Answer : 8/45
To find this answer all you have to do is multiply fractions. Multiply the numerator by the numerator and the denominator by the denominator.
4 x 2 = 8 5 x 9 = 45
This gives you 8/45.
$250*12months=$3,000
$39,000/$3,000=13
So 1/13 of her yearly income is spent on entertainment.
