Answer:
300
Step-by-step explanation:
X^2=10×10=100
3×100=300
Complementary angles, sum = 90
So 3y - 4 + 73 = 90
3y + 69 = 90
3y = 21
y = 7
Answer
y = 7
Susana=s
maria=m
m= 3s/5
s+m=56
s+(3s/5)=56
(5s+3s)/5=56
8s=56*5
8s=280
s=280/8
s=35
35 --->5/5
x ---> 3/5
x= (3/5)*35 / (5/5)
x=21
edad de maria= 21 años
