Answer:
1) [tex]\sqrt{106}[/tex]
2) [tex]\sqrt{187[/tex]
3) x=30
4) x= -4/3
Step-by-step explanation:
Use the Pythagorean theorem to find the missing angle.
In the formula, the c is the length of hypotenuse, so
[tex]c=\sqrt{9^2+5^2} \\c=\sqrt{106}[/tex]
[tex]3^2+b^2=14^2\\b^2=196-9\\b=\sqrt{187}[/tex]
20*9=6x
180=6x
x=30
4(3x+2)=6x
12x+8=6x
6x=-8
x= -4/3
