Answer:
That would be the second triangle.
Step-by-step explanation:
It's not the fourth triangle.
It is the second (45-45-90) triangle. It has 2 equal sides so
sin 45 = opposite / hypotenuse and cos 45 = adjacent / hypotenuse and the opposite = adjacent side, making the cosine and sine the same value.
Answer:
x= - 41/6, y= -6/23
Step-by-step explanation:
2x - 3y= - 1 ...(1)
0.8x - 3.5y=1/5 ...(2)
(2)×10 : 8x - 35y= 2 ... (3)
(1)×4 : 4x-12y= - 4 ...(4)
(3)-(4): 8x-35y=2
8x-12y= -4
_________
- 23y= 6
y= - 6/23
Substitute y= - 6/23 into any equation
Exp : 2x - 3(-6/23) = - 1
2x+18/23 = - 1
2x = - 41/3
x= - 41/6
