Answer:
22.6°
Step-by-step explanation:
the cosines rule :
cos x = (24²+26²-10²)/2(24)(26)
= (576+676-100)/1248
= 1152/1248
= 0.923
so, x = cos`¹ 0.923 = 22.6°
Answer:
Step-by-step explanation:
I assume the equation is
√(2x - 5) - √(x + 6) = 0
Note the domains for the root expressions:
• √(2x - 5) : 2x - 5 ≥ 0 ⇒ x ≥ 5/2
• √(x + 6) : x + 6 ≥ 0 ⇒ x ≥ -6
So any valid solution we find must be at least 5/2.
Move one term to the other side.
√(2x - 5) = √(x + 6)
Take squares.
(√(2x - 5))² = (√(x + 6))²
2x - 5 = x + 6
Solve for x :
x = 11
