Answer:
1) 25
2) 20
Step-by-step explanation:
1)
Since these are vertical angles, they are congruent. Therefore, 3x=75, and x=25 degrees.
2)
Once again, these are vertical angles.
2+3x=62
3x=60
x=20 degrees
Hope this helps!
Ratio of Anne : Mark : Ben = 20 : 35 : 25
= 4 : 7 : 5 ( total 16 parts )
Anne = 4/16 x £80 = £20
Mark = 7/16 x £80 = £35
Ben = 5/16 x £80 = £25
We know that
in a right triangle
cos θ=adjacent side angle <span>θ/hypotenuse
in this problem
</span>adjacent side angle θ=38 in
hypotenuse=40 in
cos θ=38/40
θ=arc cos (38/40)-------> 18.19°-------> 18°
the answer is
18 degrees
