Answer:
50
Step-by-step explanation:
30÷60=0.5
0.5×100=50
you can reverse it so
50÷100 is 0.5
so 1 percent of 50 is 0.5
so 60 percent of 50 is 30
0.5×60=30
x=30/0.6 = 50
30°
<4=<2=30
(vertical opposite angles are equal)
the answer is 320

76 rounded to 1 s.f. is 80
46 rounded to 1s.f. is 50
80+50+80+50= 260
Hope this helps!
