Answer:
75% of students are year 7
Step-by-step explanation:
divide 126 by 168 which equals 75% of year 7 pupils
So a right triangle is 90° and we have a 45° angle every triangle=180° so 90+43=133
180-133=47° the other angle is 47°
Answer:
Subtract 60 from the sum of 8e and 20 when e=7
8e +20
8(7) + 20
56+20=76
76-60=16
Nothing more can be done to this problem, it stays the same.
