Angle C must equal 79 degrees because there are 180 degrees in a triangle.

Use the sine rule to find side b:

15/sin79 = b/sin63

b = 15*sin63/sin79 = 13.61524832 units

Use 1/2*c*b*sin38 to find the area:

1/2*15*13.61524832*sin38 = 62.86787901 square units

The area of angle LMN is 113cm2 LM 21cm and MN 21 cm Angle LMN is acute Calculate these angles A LMN B MNL I know that LMN is 42.3 but I need to know MNL?

To find angle MNL, you can use the area formula for a triangle: Area = 0.5 × base × height. Given the area (113 cm²) and sides LM (21 cm) and MN (21 cm), you can calculate the height from point L to line MN. Assuming angle LMN is 42.3 degrees, you can then use the sine rule or the fact that the sum of angles in a triangle is 180 degrees to find angle MNL. Thus, angle MNL = 180° - (angle LMN + angle LNM). If angle LNM is calculated as approximately 95.7 degrees, then angle MNL would be approximately 42 degrees.

This is not a triangle. All three angles of any triangle must always add up to 180o. The angles you gave add up to only 59.9o.


Can you work out the area of any triangle using bxh divided by 2?

Yes, that works for any triangle. The height always has to be at a right angle to the base. If there is an angle over 90 degrees, you may have to extend the base.Yes, that works for any triangle.
