Answer:
The answer would be: D. (1,2) and (2,-1)
Answer:
just circulate little numbers of the answers bellow -_-
Step-by-step explanation:
cause u said "does anyone know how to do the first question?"
Step-by-step explanation:
given,
the complete angle is complementry angle which is 90°
let the first angle be x and second angle be 7x ( as second angle is 7 times more than first angle )
now,
→ x + 7x = 90
→ 8x = 90
→ x = 90/8 = 11.25
therefore
1st angle = x = 11.25°
2nd angle = 7x = 7 × 11.25 = 78.75°
hope this answer helps you dear take care and may u have a great day ahead!
Let angle = x
sinx = 43.2/72.5
=> x = 36.57 degrees
