I will solve one for you to get you a idea so next u can solve all
To know whether line is tangent toa circle or not we should know that that line is a tangent line of a circle if it intersects circle at single point.
and this will always be perpendicular at radius
so in problem
1)
diameter is given 7.5
and u can see they make a right triangle ABC if that is perpendicular so segment AB is tangent to a circle.
Lets see by applying <span>Pythagorean Theorem
</span>this is method we can say that this is in fact a right triangle
a^2=b^2=c^2
a,b are shorter side c is longer side
(7.5)^2+(8)^2=(17)^2
56.25+64=289
120.25=289
both are not equal so they are not forming right triangle so segment AB is not a tangent line.
$47.88 your answer and I am the most important person in the world.
Answer:
i think a but not sure
Step-by-step explanation:
i always second guess myself but a was first answer for me
The correct answer would be $1.28
Answer:
48
Step-by-step explanation:
To find one fourth, I divided 64 by 4, which gave me 16. Then, to find 3/4, I multiplied 16*3, which is 48.
