In the pictured triangle, 2A is 98 degrees and 2B is 12 degrees. If side a is 84
units long, approximately how long is side b?

The length of the side b is 17.82 units

Explanation:

Given that the triangle has ∠A = 98° and ∠B = 12°

Also, given that the side a has length a = 84 units

We need to determine the length of the side b

To determine the length of the side b, we shall use the law of sine formula.

The law of sine formula is given by

Substituting the values in the above formula,we have,

Simplifying, we get,

Cross multiplying, we get,

Multiplying, we get,

Dividing both sides by 0.99, we get,

Thus, the length of the side b is approximately 17.82 units.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

x=5

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
