Answer 1

Answer:

a) 30

b) 0.225

c) supplementary

d)

e)

Answer 2

Answer:

a)The value to be subtracted from 20 to get - 10 is:

= let the value be x.

so we get the equation,

$20 - x = - 10 \\ x = 20 + 10 \\ x = 30\\ option \: 2 \: is \: correct$

b) The value of ' zin 1.5 = is:

what is zin ?

c) The adjacent angles in a parallelogram are -

= supplementary

option 2 is correct.

d) The value of 'x' in the given figure is -

= supplementary angle of 125° = 55°

55° and 55° are the remote interior angles of an exterior angle x.

so using the property,

( An exterior angle is the sum of its remote interior angles of triangle )

x = 55° + 55°

x = 110°

so option 3 is correct.

e) the other number of the Pythagorean triplet 32 +4 is -

= Pythagorean triplet,

${3 \:}^{2} + {4 }^{2} = 9 + 16 \\ \: \: \: \: \: \: \: \: \: = 25 \\ {3 + {4}^{} }^{2} = {5}^{2}$

so option 2 is correct.

Hope this will help u.

Do well .. ALL THE BEST ..
