Answer:
Step-by-step explanation:
Area of triangle = 1/2 * base * height
Use the side of length 5.6cm as base, the height will be a perpendicular line from the base to the tip of the triangle.
From the right-angle triangle formed by the height and the side of length 3.9cm,
sin(56°45') = height / 3.9
height = 3.9*sin(56°45')
Substituting back into the area equation:
Area = 1/2*5.6*3.9*sin(56°45')
= 9.0cm^2
= 9cm^2

thx for the 32 points
Step-by-step explanation:
Answer:
G(-3) = -12, and F(-3) = -10.
Step-by-step explanation:
G(n) = 3n - 3
G(-3) = 3(-3) - 3, which is equivalent to -9 - 3, or -12.
F(n) = 2n - 4
F(-3) = 2(-3) - 4, which is equivalent to -6 - 4, or -10.
The answer is A. y=190-7x
Answer: 1375
Step-by-step explanation:
70-2= 70
70/2=35 (x=35)
4x=140
x^35=1225
1225+140=1375
