Your friend is 1.56 m y'all. how many millimeters tall is your friend?

1560 millimeters tall is friend's height.                

Step-by-step explanation:

Given :  Your friend is 1.56 m tall.

To find : How many millimeters tall is your friend?

Solution :

According to question,

We have to convert the unit m into unit mm.

We know that,

1 m=100 cm

1 cm=10 mm

So, 1 m = 100 × 10=1000 mm

Friend's height is 1.56 m

Converting into mm we have to multiply it by 1000.

Therefore, 1560 millimeters tall is friend's height.

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
