Answer:
C
Step-by-step explanation:
:)
Answer:
B
Step-by-step explanation:
X=2t
y=1-t
t=x/2
y=1-x/2
y=(-1/2)x+1
Step-by-step explanation:
the area of a triangle is always
baseline × height / 2
where baseline and height are perpendicular (at a 90° angle) to each other.
so, in our case the area is
7 × 2 / 2 = 7 × 1 = 7 units²
Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180
x + 75 + 40 = 180
x = 180 -75 - 40
x = 65
