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:
D: 25 miles
Step-by-step explanation:
Pythagorean Theorem:

36^2 + b^2 = 39^2
1,296 + b^2 = 1,521
b^2 = 225
b = 25
Answer:
300
Step-by-step explanation:
27% = 81
1% = 81/27 = 3
100% = 100x3 = 300people
Answer:
77 degrees
Step-by-step explanation:
The interior angles of a triangle always add up to 180 degrees, so you can form an equation:
