Answer:

-7/5.

Step-by-step explanation:

Leave the denominators the same and subtract only the numerators. Since -3 is negative and 4 is a positive being subtracted, you get -7 as the numerator. So, it's -7/5.

In AABC, MLA = 53, m4C = 84, and side a = 8 inches. Find the length of side b to the nearest tenth of an inch.
Cerrena [4.2K]

Answer:

6.8 inches

Step-by-step explanation:

Given data :

m∠ A = 53°  ,  m∠ C = 84° , side a = 8 inches

therefor m ∠ B = ( 180 - (84 + 53 )) = 43°

<u>Find the length of side b </u>

we will apply sine rule here

\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}

= \frac{8}{sin53}  = \frac{b}{sin43}

∴ b = ( sin43° * 8 ) / sin53°

      = ( 0.6819 * 8 ) / 0.7986

      = 5.4552 / 0.7986 = 6.83 ≈ 6.8 inches
