The answer is 3/25 or .12. Use the formula 1/2bh to find the area of triangles.
1/2(.4)(.6)
1/2(.24)
.12
hope that helps :)
Answer:
x, y. and 40 are the angles of a triangle.
x+y+40=180
x+y=140
difference between x and y is 30.
x−y=30 (2)
2x=170
⇒x=85
Substitute this value n equation (2), we get
85−y=30
⇒y=85−30
⇒y=55
angles of a triangle are x=85, y=55 and 40.

Answer:
B. -√2/2.
Step-by-step explanation:
This is in the third quadrant so the sine will be negative.
The hypotenuse = √ [( -3)^2 + (-3)^2]
= √18 = 3√2.
Therefore the sine = -3 / 3√2.
= -1 / √2
= -√2/2..
