Answer:
A. 12.28 km²
Step-by-step explanation:
The area of the figure is the sum of the areas of its parts. The area of the triangular part is ...
A = 1/2bh
A = 1/2(3 km)(4 km) = 6 km²
__
The area of the semicircular part is ...
A = 1/2πr²
A = 1/2(3.14)(2 km)² = 6.28 km²
__
Then the area of the figure is ...
6 km² + 6.28 km² = 12.28 km²
Ik that it isn’t one I think it is three and Ik it is the last one I think that is that right one
To convert this equation into slope intercept form simply distribute the number of -2 and put it in
Y = mx + b form
Y + 4 = -2(X-1)
Y + 4 = -2x + 2
Y = -2X + 2 - 4
Y = -2X - 2
I believe this is the solution in slope intercept form.
The answer would be 5 cuz 5 x 40 = 200
Answer:
50°
Step-by-step explanation:
All quadrilaterals' interior angles sum to 360°:
(x + 15)° + (2x + 15)° + (3x - 20)° + x° = 360°
x + 15 + 2x + 15 + 3x - 20 + x = 360
7x + 10 = 360
7x = 360 - 10
7x = 350
x = 50°
