Answer:
Step-by-step explanation:
we are given that given that 1/2T = 60 so T=120° so we also know R = 120 °
then W and S are also the same angle so 2z +240 = 360
2z = 120
z=60
W =60 °
S = 60 °
which makes sense b/c the small triangles also tell us that the sharp angles of the small triangles are 30 ° for the 30 , 60 90 triangle.
so by complementary angle we know that c = 60 °
we also know that a = 12 b/c all the small triangles are identical.
we also know that b= 90 ° also by complementary angle
we can also solve for length of SW and RT
cos(30)=adj / Hyp
12*Cos(30) = adj
12* /2 = adj
but the adjacent side is 2 times for SW so
SW = 12
for RT
sin(30) = Opp / hyp
12 * Sin(30) = Opp
12 * 1/2 = opp
but RT is times 2 again, sooo
RT = 12
you can also solve for the area of SRWT = 12 *12 = 144 units (what ever unties 12 is in) hmmm
That's all I can think of to solve for now :)
