Use the net as an aid to compute the surface area of the triangular prism.
Harrizon [31]

Answer:

Option C. 564\ mm^{2}

Step-by-step explanation:

we know that

The surface area of the triangular prism using the net is equal to the area of two triangles plus the area of three rectangles

so

SA=2(\frac{1}{2})(10)(12)+2(13)(14)+(10)(14)

SA=60+364+140

SA=564\ mm^{2}

(2y + 50)" (7x - 248)<br> (5y - 17) (x +44)°<br> Find the value of x and y.
Sveta_85 [38]

Answer:

x = 48

y = 21

Step-by-step explanation:

To find the value of x and y, using the definition of supplementary angles, create an equation to find x and y as follows:

Finding y:-

(2y + 50) + (5y - 17) = 180 (supplementary angles definition)

Solve for y

2y + 50 + 5y - 17 = 180

Collect like terms

2y + 5y + 50 - 17 = 180

7y + 33 = 180

7y + 33 - 33 = 180 - 33

7y = 147

\frac{7y}{7} = \frac{147}{7}

y = 21

Finding x:-

(7x - 248) + (x + 44) = 180 (supplementary angles definition)

Solve for x

7x - 248 + x + 44 = 180

Combine like terms

8x - 204 = 180

8x - 204 + 204 = 180 + 204

8x = 384

\frac{8x}{8} = \frac{384}{8}

x = 48
