Answer:
There are 76 students:
g + b = 76
girls is 13 more than twice the boys:
g = 2b + 13
replace g with 2b + 13 in 1st equation
2b+13+b = 76
3b + 13 = 76
3b = 63
b = 21 boys
g = 76-21 = 55 girls
Step-by-step explanation:
Since the standard form of the circle is:
(x-h)^2+(y-k)^2=r^2, and (h,k)=(0,0) and r=10 so we have:
x^2+y^2=100 Looking at the points you have:
(√10, 0) does not work as (√10)^2+0^2=10+0=10
(0, 2√5) does not work as 0^2+(2√5)^2=0+20=20
(5√2, 5√2) works as (5√2)^2+(5√2)^2=50+50=100
Answer:
The answer is 0
Step-by-step explanation:
I took the test
third side =√{30²+16²)=34
sin theta/2=16/34
theta/2=sin-¹(16/34)
theta=28.07×2=56.14
