Answer: d=42
Step-by-step explanation:
Both angles are in a supplementary (straight with 180 degrees) line bisected by an angle, so use the supplementary angle theory
(d+7)+(3d+5)=180
4d+12=180
4d=168
d=42
Step-by-step explanation:
sec² x − 2 = 0
sec² x = 2
cos² x = ½
cos x = ±√½
x = π/4, 3π/4, 5π/4, 7π/4
