Sam and Harry are family. Sam is currently is three times Harry's age. Sam's age is also 10 more than twice Henry's age. What ar
kramer

Answer:

<em>Sam is 30 years old, and Harry is 10 years old.</em>

Step-by-step explanation:

Let us assume that the age of Sam is x and the age of Harry is y.

Sam is currently is three times Harry's age.

So, x=3y  ----------------------1

Sam's age is also 10 more than twice Harry's age.

so, x=2y+10  ---------------2

Subtracting 2 from 1, we get

\Rightarrow x-x=3y-2y-10

\Rightarrow 0=y-10

\Rightarrow y=10

putting this in equation 1,

x=3(10)=30

Therefore, Sam is 30 years old, and Harry is 10 years old.

Lines that appear to be tangent are tangent. O is the center of the circle. What is the value of x?
MatroZZZ [7]

Answer:

28

Step-by-step explanation:

Neat Question.

Thanks for posting.

The straign line (horizontal) makes an isosceles triangle inside the circle. So the bottom angle of the triangle is also 59 degrees. The central angle of the interior triangle is

180 - 59 - 59 = 62.

x and the 62 degree angle are complementary -- both are in the 90 degree angle triangle made by the tangent. x + 62 = 90

x = 90 - 62 = 28
