Step-by-step explanation:
90x5=450
548-450=98
98divede12=8..2
T = varsta tatalui
f = varsta fiului
anul acesta: t = 4 x f
peste 20 de ani: t+20 = 2 x (f+20)
=> 4 x f +20 = 2 x f + 2 x 20
4 x f - 2 x f = 2 x 20 - 20
2 x f = 20
f = 10
anul acesta fiul are 10 ani
peste 5 ani fiul va avea...
Answer:
30 i think
Step-by-step explanation:
We need the actual problem/diagram or whatever to solve this
Angle A = (arc CD - arc BC) / 2
56 degrees = (arc CD -95) / 2
112 degrees = (arc CD -95)
arc CD = 207
