1 answer:

7 0

9a-2b=-8.....1
-7a+3b=12.....2

So,
1 equation into 3 and 2 equation into 2.

Then,
18a-6b=-24
-14a+6b=24.

4a=0 a=0 .

Substitute a value in 2 equation.

b=4.

#2 Find the segment length indicated. Assume that lines which appear to be tangent are tangent. *

gregori [183]

The angle of a tangent and a radius is a right angle.

The missing length would be the hypotenuse. Use the Pythagorean theorem to solve.

X = SQRT(12^2 + 16^2)

X = SQRT(144 + 256)

x = SQRT(400)

X = 20
