The pythagorean theorem says that a² + b² = c²
You're given the b and the c so substitute the values in: a² + 12² = 15²
a² + 144 = 225; subtract 144 from both sides
a² = 81; square root each side
a = 9, or choice C
This is the answer in different units
Millimeters-7660.46
Centimeters-766.046
Meters-7.66047
Kilometers- 0.00766046
Inches-301.593
Feet-25.13
Yards- 8.37758
Can you show me a picture of the choices?
Answer:
x =27
Step-by-step explanation:
from Z angls rule the agle (BDE) =72
and total angl on D =180
so, 2x +2x+72=180
4x = 180 -72
4x = 108 (divied both sides by 4)
x= 27
The Correct Answer Is B.36 square centimeters
Hope this helps
