Find x. Give reasons to justify your solution. b Lines AB and CD are straight lines.

MArishka [77]

Answer:

x = 28

Step-by-step explanation:

Given that lines AB and CD are straight lines that intersects at O, it follows that the pair of opposite vertical angles formed are congruent.

Thus,

<AOD = <BOC

<AOD = 152°

<BOC = 3x + x + (x + 12) (angle addition postulate)

<BOC = 5x + 12

Since <AOD = <BOC, therefore,

152° = 5x + 12 (substitution)

152 - 12 = 5x (subtraction property of equality)

140 = 5x

140/5 = x (division property of equality)

28 = x

x = 28

Look at multiples of 7 and you’ll find 91.

91 dived by 3 is 30 with a remainder of 1.

91 divided by 5 is 18 with a remainder of 1.

91 divid by 7 is 13 with no remainder.

Is 8 the HCF of 32, 48 and 72?

Sergio [31]

Step $1$

<u>Find the factors of each number</u>

we know that

$32=2^{5} \\48=2^{4}*3\\72=2^{3}*3^{2}$

Step $2$

<u>Find the greatest common factor (GCF)</u>

the GCF is equal to----------> $2^{3}=8$

therefore

<u>the answer is</u>

The GCF is $8$
