Question

suppose ( mangle a = 290 ) degrees. then ( angle a ) is an angle quadrant in one two three four the reference angle for ( angle a ) is degrees. question help: video written example

Explanation:

Step1: Determine quadrant range

Quadrant IV: $270^\circ < \theta < 360^\circ$
$270^\circ < 290^\circ < 360^\circ$, so Quadrant Four.

Step2: Calculate reference angle

Reference angle for Quadrant IV: $360^\circ - \theta$
$360^\circ - 290^\circ = 70^\circ$

Answer:

D. Four
70
