Answer:

38.7

Step-by-step explanation:

\frac{sinA}{A}=\frac{sinB}{B}=\frac{sinC}{C}

A, B and C are the sides of the triangle and sinA, sinB and sinC are the opposing angles

\frac{sin95}{43}=\frac{A}{27}

A = sin^{-1} (\frac{27*sin95}{43} )=38.72018809

Find the area of a triangle whose sides are 3cm,6cm and 7cm
nadya68 [22]

Answer:

See below

Step-by-step explanation:

It is NOT  a RIGHT triangle so you <u>cannot use</u>   1/2 b * h

 but you can use Heron's Formula

Area = sqrt( s (s-a)(s-b)(s-c) )

s = semi- perimeter =   (3+6+7)/2 = 8

Area = sqrt ( 8 ( 8-3)(8-6)(8-7) )   = sqrt ( 80) = 8.9 cm^2
