Step-by-step explanation:

interior angle of regular polygon = [ ( n − 2 ) × 180 ] / n

n = number of sides

hence, in b), n = 6

interior angle of regular polygon = [ ( 6 − 2 ) × 180 ] / 6 = 120

#26 What are the solutions to the equation 4x2 - 52x + 169 = 121?

Sloan [31]

Answer:

D. {1, 12}

Step-by-step explanation:

4X^2-52x+169=121

The equation can be summarized thus:

4X^2-52x+169-121=0

4X^2-52x+48=0

divide the each number of the equation by 4

4X^2/4-52x/4+48/4=0

x^2-13x+12=0

we need to numbers that when we multiply them the result is 12 and -13 when we add together

-1 and -12(-1-12=-13 and -1*-12=12)

x^2-x-12x+12

x(x-1)-12(x-1)

(x-1)(x-12)

x-1=0 or x-12=0

x=1 or x=12

Find the surface area of the square pyramid 8mm 6mm

bija089 [108]

Answer:

136 mm²

Step-by-step explanation:

$A=a^{2} +2a\sqrt{\frac{a^{2} }{4} } +h^{2}$

$A=6^{2} +2(6)\sqrt{\frac{6^{2} }{4} } +8^{2}$

$A=36 +12\sqrt{\frac{36 }{4} } +64$

$A=36 +12\sqrt{9 } +64$

$A=36 +12(3)+64$

$A=36 +36+64$

A = 136
