The problem is attached to this post, basically i need the exterior reactions and how to work them out.(adsbygoogle = window.adsbygoogle || []).push({});

i know i need to take moments im just not sure how to work it out.

Basically what i worked out

is

i assumed horizontal members are equally to 1

sum of the horizontal = 0 5Kn- HA - HE=0

Sum of the vertical =0 10KN- VA =0

But that is where im stuck i know the numbers should be roughly

HA=20

VA= 10

HE = 15

But i know it is more accurate than that im not sure if i need to include sine or cosine in the solution

Thanx in advance
