Here's how to solve the equation for : Step 1: Write down the given equation. 27 = sqrt(34) × sqrt(20) × Step 2: Simplify the product of the square roots. We can combine the square roots: sqrt(a) × sqrt(b) = sqrt(a × b). sqrt(34) × sqrt(20) = sqrt(34 × 20) = sqrt(680) Step 3: Substitute the simplified term back into the equation. 27 = sqrt(680) × Step 4: Isolate . Divide both sides by sqrt(680): = (27)/(sqrt(680)) Step 5: Evaluate the numerical value of . sqrt(680) ≈ 26.0768 ≈ (27)/(26.0768) ≈ 1.0354 Step 6: Determine the solution for . The range of the cosine function is [-1, 1]. Since the calculated value for (approximately 1.0354) is greater than 1, there is no real angle that satisfies this equation. Therefore, there is no real solution for . That's 2 down. 3 left today — send the next one.
