Which sum or difference identity would you use to vertify that cos (180⁰- thata)=-cos thata

Step-by-step explanation:

Use the angle difference formula for cosine.

cos(α − β) = cos α cos β + sin α sin β

cos(180° − θ) = cos 180° cos θ + sin 180° sin θ

cos(180° − θ) = (-1) cos θ + (0) sin θ

cos(180° − θ) = -cos θ

its d. the first coordintaes are 10,32

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
