Answer:
53 degrees
Step-by-step explanation:
to start the 11 + 3x is going to equal the 170 then take the two numbers and solve for x
11 + 3x = 170
minus 11 from both sides
3x = 159
divide by 3 on both sides
x = 53 degrees
in this kind of exercises you need to work in 3 steps:
1. split your figure into shapes you know
2. calculate the area of those separate shapes
3. add the areas
1. (see picture)
2. shape 1 (triangle)
A= 8m×3m
A= 24m²
2. shape 2 (rectangle)
A= 8m×4m
A= 32m²
3.
total A= A1+ A2
A= 24m²+32m²
A= 56m²
10x12 = 120
10x15 = 150
10x18 = 180 and so on.
The answer is that the area of the rectangle increase by 30 cm every minute!
Answer:
Step-by-step explanation:
You just need the distance formula here. It's very simple to follow:

which, for us, looks like this:
