There's no diagram here so I can't be specific, but I've attached an image.

The area of the base of a prism is 24 mm2. The perimeter of the base is 22 mm. The height of the prism is 5 mm.
DIA [1.3K]
The surface area = The area of the two bases + the area of the lateral surface

The area of 1 base = 24 mm², so the area of two is 48 mm².

The area of the lateral surface = the perimeter of the base × the height.
The perimeter = 22 mm. The height = 5 mm.
Thus the lateral surface area is 110 mm².

The total surface area is 110 + 48 = 158 mm².

Which angle measures are correct? Select three options. mAngle2 = 125° mAngle3 = 55° mAngle8= 55° mAngle12 = 100° mAngle14 = 100
RUDIKE [14]

Answer:

<em>m<2  = 125°, m<8 = 55° and m<14 = 100°</em>

Step-by-step explanation:

The question is incomplete.

<em>Lines e and f are parallel. The mAngle9 = 80° and mAngle5 = 55°. Parallel lines e and f are cut by transversal c and d. All angles are described clockwise, from uppercase left. Where lines e and c intersect, the angles are: 1, 2, 4, 3. Where lines f and c intersect, the angles are 5, 6, 8, 7. Where lines e and d intersect, the angles are 9, 10, 12, 11. Where lines f and d intersect, the angles are 13, 14, 16, 15. Which angle measures are correct? Select three options. mAngle2 = 125° mAngle3 = 55° mAngle8= 55° mAngle12 = 100° mAngle14 = 100</em>

Given

m<9 = 80°

m<5 = 55°

From the diagram, m<5+m<6 = 180°

Substitute m<5 = 55° into the formula, to get m<6

55+m<6 = 180

m<6 = 180-55

m<6 = 125°

From the diagram m<6 = m<2  = 125° (corresponding angles)

<em>Also on line e</em>, m<9 = m<12 = 80° (vertically opposite angles)

On line f, m<14+m<16 = 180° and m<12 = m<16 = 80

m<14+80°  = 180°

m<14 = 180-80

m<14 = 100°

<em>Also on line f</em>, m<5 = m<8 (vertically opposite angles)

Since m<5 = 55°, m<8 = 55°

Also on line e, m<10 + m<12 = 180

Since m<2 = m<10 = 125° (corresponding angle)

To get m<12,

125+m<12 = 180

m<12 = 180-125

m<12 = 55°

Also m<10 = m<14 = 125° (corresponding angle)

On line e, m<10 = m<11 = 125°  (vertically opposite angle)

Also on line e, m<3 = m<11 (corresponding angle)

This shows that m<10 = m<11 = m<3 = 125°

<em>From the above calculation the angle measure that are correct are:</em>

<em> m<2  = 125°, m<8 = 55° and m<14 = 100°</em>

A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?
julia-pushkina [17]
For the answer to the question above, a system of equations has no solution when the lines representing the equation are parallel but do not coincide. For two lines to be parallel, the must have the same gradient i.e. coefficient of x when y is made the subject of formula must be equal.
If one of the equations is
y = 8x + 7,
then the other equation will be
y = 8x - 7
