Lets x = measure of the second angle, so m<2 = x
m<1 = 2x (<span>the measure of the first angle is twice the measure of the second angle)
</span>m<3 = x + 96 (<span>96 degrees more than the measure of the second angle)
</span>
x + 2x + x+ 96 = 180
4x + 96 = 180
4x = 84
x = 21
2x = 2(21) = 42
x + 96 = 21+96 = 117
answer
m<1 = 42
m<2 = 21
m<3 = 117
Double check
sum = 180
m<1 + m<2 +m<3 = 180
42+21+117=180
180=180
Answer:
The area of the circle is 314 inches
Step-by-step explanation:
Area if a circle = πr²
r = radius
r= d/2
r=20 /2
r=10 inches
Area =3.14×10²
= 3.14×100
=314 inches
Answer:
Step-by-step explanation:
Use for the equation of a circle in standard form with radius and center . Therefore, the equation of the circle in standard form is
We can simplify this equation using logaritmic rules. logx-logb = log(x/b)
than our equation becomes.
log3((18x^3)/(2x)) = log3(144) or
log3(9x^2) = log3(144)
for x= -4 we get that left side is equal to right side
log3(9*(-4)^2) = log3(144)
but if you put that value of x=-4 in start you will get log3(18(-4)^3) which is log of negative value which is imposible. That is why x=-4 is extraneous solution.
Answer:
-4
