Question

please tell answet I am in 6 grade​

Answer 1

Step-by-step explanation:

FIRST WE NEED TO KNOW THAT ANGLE IN A STARIGHT LINE IS 180°.

a) <POR=76° , <SOP=?

SINCE THE BOTH ARE IN A STRAIGHT LINE THEREFORE THEY ARE SUPPLEMENTARY (180°).

<POR+<SOP=180°

=76°+<SOP=180°

=<SOP=180°-76°

<SOP=104°

<SOP=104°

b)

GIVEN THAT <POR=2/5 OF RIGHT ANGLE (2/5 OF 90°)

=2/5×90

=36°

<POR=36°

THIS IS SAME LIKE THE FIRST PROBLEM.

<POR+<SOP=180°

36°+<SOP=180°

<SOP=180°-36°

<SOP=114°

<SOP=114°
