Answer:
b = 6√15
Step-by-step explanation:
6² + b² = 24²
36 + b² = 576
b² = 540
b = √540
b = √9 · √60
b = 3 · √60
b = 3 · √4 · √15
b = 6 √15
Answer:
155 degrees
Step-by-step explanation:
10 x 8 = 80
80 + 75 = 155
The number that should be added to both sides is 16 because its half of b, which is then squared. You then get (x+4)^2=20, which you then square root both sides and get x+4=+-20 and then subtract the 4 to get x=-4+-20
