Solve the equation for 0° ≤ x ≤ 90°. Round to the nearest degree. 8cotθ + 3 = 5

galina1969 [7]

Answer:

θ = 76°

Explanation:

The given equation is:

8 cotθ + 3 = 5

8 cotθ = 5-3

8 cotθ = 2

cot θ = $\frac{2}{8} = \frac{1}{4}$

Now, we find θ

We know that the cot function is the inverse of the tan function.

The tan of an angle is positive in the first and third quadrants, therefore, the cot will be positive in the first and third quadrants as well

Now, we are given the condition:

0° ≤ x ≤ 90°

Therefore, we know for sure that our angle is in the first quadrant

θ = cot⁻¹( $\frac{1}{4}$ ) = 75.96° = 76° to the nearest degree

Hope this helps :)

Help! Which estimate is closest to the actual value of ( 2.99548 ) ⋅ ( 1.8342 )?

nordsb [41]

Answer:

Step-by-step explanation:

2.99548 * 1.8342

the first number rounds to 3.....the second number rounds to 2.....3 * 2 = 6...but it will be a little short of 6 because of the 1.8.....so I am going with 5.5

===============================

jada ran 7.1 miles.....noah ran 5.123 miles

so jada ran (7.1 - 5.123) = 1.977 miles farther then noah

===============================

greater then 3...

1.67 + 1.4 and 4.5 - 1.47
