Answer:
a = 15
Step-by-step explanation:
Step-by-step explanation:
1. a²=25²-15²
a²=(25-15)(25+15)
a²=10×40
a=20
2.b²=10²-6²
b²=(10-6) ×(10+6)
b²=4×16
b=8
The best angle relationship that describes angles BAC and EAF is supplementary angles
The sum of angle on a straight line is supplementary i.e. they sum up to 180 degrees.
If Angles BAE and FAC are straight angles, it means they are linear pairs and their sum is 180 degrees. Mathematically;
m<BAE + m<FAC = 180degrees
Hence we can conclude that the best angle relationship that describes angles BAC and EAF is supplementary angles
