The general formula for a tangent and secant is

tangent^2 = external segment * full length of the secant.

Givens

tangent length = x

external segment = 7

secant length = 7+ 21

Formula

x^2 = 7 * (7 + 21) Remove brackets

x^2 = 7 * 28 Combine

x^2 = 196 Take the square root of both sides

√x^2 = √196

x = 14

Answer: <u>x = 14</u>

Convert. 2/3and 4/6 into like fraction

Luden [163]

Answer:

Answer given below

Step-by-step explanation:

When we calculate the LCM, you get it as 6.

So both the fractions should have a denominator 6.

For that, in 2/3 we should multiply both numerator and denominator with 2 so that denominator becomes 6.

When we convert to like fraction, 2/3 becomes 4/6.

Now both the fractions have common denominator

Hope it helps.

In December it snowed 2 days for every 8 days it did not snow what percent of the days in December did it snow

sergey [27]

I think it might be 20%. If in a total of 10 days it only snowed 2, then you could take 2/10, which is .2, then multiply by 100 to make it a percentage... which would be 20%.
