Find a if b=5 and c=8cm

Mathematics

snow_tiger [21]3 years ago

Using the Pythagorean theorem:

a = √(c^2 - b^2)

a = √(8^2 - 5^2)

a = √(64 - 25)

a = √39 ( Exact answer )

Or √39 =  6.244997 as a decimal and you round the decimal answer as needed.

Find the value of x .. assume that segments that appear to be tangent are tangent .
Rus_ich [418]

Answer:

sqrt(277) =x

x is approximately 16.64331698

Step-by-step explanation:

This is a right triangle since 14 is tangent to the circle and 9 is a radius

We can use the Pythagorean theorem to solve this problem

a^2 +b^2 =c^2

9^2+14^2 =x^2

81+196 = x^2

277 = x^2

Taking the square root of each side

sqrt(277) = sqrt(x^2)

sqrt(277) =x
