There are six

It is known that △ ABC is an acute triangle, the opposite sides of ∠ B and ∠ C are B and C respectively, and ∠ B = 45 °, B = √ 2, C = √ 3. (2) find the area s △ ABC of △ ABC

b/sinB=c/sinC
sinC=√3 /2, C=60°
A=105°
Finding the area s △ ABC of △ ABC
=0.5bcsinA
=√6X（√6+√2）/8
=（√3+3）/4

It is known that the triangle ABC is an acute triangle, ∠ B = 45 ° and ∠ C = 60 ° and B = √ 2, and the area of triangle ABC is calculated

According to the sine theorem
b/sinB=c/sinC
c= b*sinC/sinB= √6
A= 180-45-60= 75
Area of triangle ABC = 1 / 2 * BC Sina = √ 3 * sin75 = √ 3 * (√ 6 + √ 2) / 4
