Answer:
95 degrees
Step-by-step explanation:
Angle S is 95 so arc QR = 95×2 = 190
Total arc is 360 degree
Now to find arc QS
arc QS + arc SR + arc QR =360
arc QR + 75 + 190 =360
arc QR = 360- 265
arc QR = 95 degrees
F=2/3 of S
F+S=310
2/3 S + S = 310
(2S + 3S)/3=310
S=[(310)(3)]/5
S=186 students taking Spanish
F=2/3 of 186
F=124 students taking French
Answer:
Now, the father is 60, and the son is 24.
Step-by-step explanation:
Now:
Father's age = f
Son's age = s
4 years ago:
Father's age = f - 4
Son's age = s - 4
In 12 years:
Father's age = f + 12
Son's age = s + 12
Now:
f = 3(s - 4)
In 12 years:
f + 12 = 2(s + 12)
We have 2 equations that we can solve in a system of equations.
f = 3(s - 4)
f + 12 = 2(s + 12)
f = 3s - 12
f + 12 = 2s + 24
f = 3s - 12
f = 2s + 12
Since above both equations are in terms of f, set the right sides equal and solve for s.
3s - 12 = 2s + 12
s = 24
f = 3(s - 4)
f = 3(24 - 4)
f = 3(20)
f = 60
Now, the father is 60, and the son is 24.
