The complement is what adds to an angle to get 90 degrees
so
x is 25 mroe than 4 times y
x+y=90
x=25+4y
sub 25+4y for x
25+4y+y=90
25+5y=90
minus 25 both sides
5y=65
divide both sides by 5
y=13
sub back
x+y=80
x+13=90
x=77 degrees
Answer:
area of semicircle only = 113.43 mm²
total area = 185.43 mm²

Answer:
A is A=2(1+2)a2
B is A≈208.18cm²
Step-by-step explanation:
A explanation is A=2(1+2)a2=2·(1+2)·102≈482.84271
B explanation is A=145(5+25)a2=14·5·(5+2·5)·112≈208.17777cm²
