Height from angles watch

1. Is there a way to calculate a height of a triangle from the pitch and length. For instance if the length it the base is 6000mm ant the pitch of each side is 50 degrees. What would the height at the point the two side cross?

The two given angles can be used to find the third angle. Then use the sine rule to find one of the other sides.

You can then use one of two right-angled triangles to find the height.

For an isosceles triangle like in your example, you can use simple trig straight away since the height splits the triangle into two congruent right-angled triangles so their base length should be obvious.
