Answer:
1232 m^2.
Step-by-step explanation:
The net consists of 2 triangles and 3 rectangles.
Area of each triangle = 1/2 * 24*7 .
Area of 1 rectangle = 25 * 19.
The other 2 have areas 24*19 and 7 * 19.
Therefore the surface area of the prism
= 2 * 1/2 * 24 * 7 + 25*19 + 24*19 + 7*19
= 1232 m^2.
Boy: x
girl: x - 53
father: 4(x - 53)
Now you simplify.
M and N are not angles but they are lines. If we are talking about lines, yes the two of them are parallel as they do not intersect.
Answer:
x = 6, y = 5
Step-by-step explanation:
5x - 4y = 19 -------> equation 1
x + 2 = 8 --------> equation 2
<u>Step 1</u> : Subtract 2 on both sides in equation 2.
x + 2 - 2 = 8 - 2
x = 6
<u>Step 2</u> : Substitute the value of x is equation 1.
5 ( 6 ) - 4y = 19
( 5 * 6 ) - 4y = 19
30 - 4y = 10
<u>Step 3</u> : Subtract 30 on both sides.
30 - 30 - 4y = 10 - 30
- 4y = - 20
<u>Step 4</u> : Multiply - 1 on both sides.
- 1 * - 4y = - 1 * - 20
4y = 20
<u>Step 5</u> : Divide 4 on both sides.
4y / 4 = 20 / 4
y = 5
<u>Hence</u>,
x = 6
y = 5
Answer:
360
Step-by-step explanation:
Because an exterior angle equal to 1 the total number of sides is equal to 360°.
