Answer:

Step-by-step explanation:

m∠1 = m∠2 {Corresponding angles}

78 - 2x = 89 - 3x

Add 3x to both sides

78 - 2x + 3x = 89

78 + x = 89

Subtract 78 from both sides

x = 89 - 78

x = 11

Alenkasestr [34]

Answer:

445.2 square cm

Step-by-step explanation:

The surface area consists of area of two bases and area of three leteral faces. Each lateral face is a rectangle with length of 23 cm and width of 6 cm.

The area of rectangle is

$A_{rectangle}=\text{length}\times\text{width}$

So,

$A_{rectangle}=23\times 6=138\ cm^2$

The area of base is given as $15.6\ cm^2$

Thus, the surface area is

$SA=2A_{base}+3A_{lateral\ face}\\ \\SA=2\cdot 15.6+3\cdot 138=445.2\ cm^2$
