Answer:
i think the answer is 7.9373
Step-by-step explanation:
so its the Herons Formula (when you know all 3 sides) so the formula would be
Area = √ p ( p − a ) ( p − b ) ( p − c )
p is half the perimeter
or,
a + b + c

I'm not positive but I think it would be C
Triangle PDQ has:
Side "p" is opposite Angle P
Side "d" is opposite Angle D = 45º + 23º = 68º
Side "q" is opposite Angle Q
Use the Law of Cosines:
d² = p² + q² − 2 • p • q • cos(D)
d² = (4.24)² + (4.24)² − 2 • (4.24) • (4.24) • cos(68º)
d² = 2(4.24)² − 2(4.24)² • cos(68º)
d² = 2(4.24)² • [ 1 – cos(68º) ]
