Tan205° = .466 tan55° = 1.428 tan25° = .466 -tan25° = " so just tan25
Answer:
Step-by-step explanation:
Let the ages be r and m
<u>We have:</u>
<u>Substitute m in the second equation and solve for r:</u>
- m = 117 - r
- 5r = 9 + 3( 117 - r)
- 5r = 9 + 351 - 3r
- 5r + 3r = 360
- 8r = 360
- r = 360/8
- r = 45
<u>Then m is</u>
2x+y=8 is the equation perpendicular to x-2y=8.
