Question

Anybody know the answer to this

Answer 1

Answer:

1)  $\sqrt{106}$

2) $\sqrt{187$

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

$c=\sqrt{9^2+5^2} \\c=\sqrt{106}$

$3^2+b^2=14^2\\b^2=196-9\\b=\sqrt{187}$

20*9=6x

180=6x

x=30

4(3x+2)=6x

12x+8=6x

6x=-8

x= -4/3
