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 :)
Step-by-step explanation:
f = 2 is the correct answer
plz mark my answer as brainlist plzzzz vote me also and hope this helps you ...
put in an positive number for x and check
2 - 5 = -3
5 - 2 = 3
- 2 + 5 = 3
5 + (-2) = 2
so the only different one is the first
1 liter of petrol in London costs £1.029
Since 1 gallon consist of 3.7854 liters, the cost of 3.7854 liters is calculated as:
Cost of 1 gallon of petrol in London = 3.7854*1.029 =£3.8951766
Next, we convert the pounds (£) to dollar($)
Since the exchange rate is 1$ =£ 0.497
£3.8951766 in $ = £3.8951766/£ 0.497 = 7.837$
The price of London petrol in dollars ($) per gallon =$7.84 (Rounded to nearest cents)
