Answer:
I believe it is 7
Step-by-step explanation:
{-2x+y=12 => y=12+2x
{3x+2y=38
3x+2(12+2x)=38
3x+24+4x=38 /-24
7x=14 /:7
x=2
y=12+2*2=12+4=16
y=16
<em>Solution: (2; 16)</em>
<em>
</em>
An angle formed by a chord and a tangent line is half the measure of the intercepted arc.
The intercepted arc is ADB, which is given as 162 degrees.
Angle EAB = 1/2 of 162
The answer is 81 degrees.
You would have to insert the number into the variable. For example,
Then, you would isolate the x value (3x).
Simplify.
Finally, divide both sides by the coefficient.
You end up with
