If b=33.2 and b=61° find a (picture provided)

For this case we have to, by definition:

This means that the tangent of angle B will be equal to the leg opposite the angle on the leg adjacent to the same angle.

Then, clearing to have:

Rounding out the value of a we have:

Option C

The correct answer is option c.  18.4

Step-by-step explanation:

Points to remember:-

Trigonometric ratio

Tan θ = Opposite side/Adjacent side

From the figure we can see a right triangle triangle ABC

To find the value of a

It is given that, b=33.2 and B=61°

Tan 61 = opposite side/Adjacent side

Tan 61 = b/a

a = 33.2/Tan 61 = 18.4

Therefore the correct answer is option c.  18.4

450 is the final answer! : )

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
