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 :)
Y = 2x - 3 . . . (1)
y = -2x + 5 . . . (2)
Equating (1) and (2),
2x - 3 = -2x + 5
2x + 2x = 5 + 3
4x = 8
x = 8/4 = 2
x = 2
y = 2(2) - 3 = 4 - 3 = 1
y = 1
Solution = (2, 1)
Answer:
6x + 2; x = 2; 6(2) + 2 = 12 + 2 = 14
