Solve the equation and it will add up to -6 so
3×-7=-21
-21-10=-31
-31+25=-6
Cos=(adjacent/hypotenuse)
So the answer will be cos(16/20) or cos(4/5) both will give u the same answer
I hope it helps
Answer:
3(360⁰)-335⁰
=1080⁰-335⁰
=745⁰ is a positive angle.
The answer is ERROR i tried it by hand and by calculator and both answers ended up as ERROR
Answer:
3 cm
Step-by-step explanation:
The ratio of areas of similar figures is the square of the ratio of linear dimensions. That means the ratio of linear dimensions is the square root of the area ratio. The ratio of the smaller triangle dimensions to the larger is then ...
k = √((8 cm^2)/(18 cm^2)) = √(4/9) = 2/3
Then the corresponding side of the smaller triangle is ...
... k · (4.5 cm) = (2/3)·(4.5 cm) = 3 cm
