In the diagram belwo, P(-8;t) is a point in the Cartesian plane such that OP=17 units and reflex $X\hat{O}P = \theta$

1. Calculate the value of $t$
2. Determine the value of each of the following without using a calculator. (a) $\cos{(-\theta)}$ (b) $1 - \sin{\theta}$

1. x^2 + y^2 = r^2

(-8)^2 + t^2=17

t= -15

2a. = cosx

= -8/17

b. = 1- -15/17

= 17/17 + 15/17

= 32/17  = 1 15/17
