Answer:

x = 6

Step-by-step explanation:

In triangle ABC, BD is the bisector of angle ABD.

Therefore by angle bisector property:

\frac{x}{8}  =  \frac{3}{4}  \\ x =  \frac{8 \times 3}{4}  \\ x = 2 \times 3 \\ \huge \red{ \boxed{ x = 6}}

Solve the triangle. Round side measure to the nearest tenth and angle measures to the nearest degree.
shutvik [7]
First calculate the missing angle \alpha. By knowing all angles in triangle have a sum of 180°.

\alpha=180-(\gamma+\beta)
\alpha=180-(90+49)=\boxed{41}

Now we required to use angle functions in a right triangle. The cosine of \beta is equal to the relation of side a and hypotenuse c.

Now we solve this for hypotenuse.

\cos(\beta)=\frac{a}{c}

c=\frac{a}{\cos(\beta)}

Now put in the numbers.

c=\frac{9}{\cos(49)}\approx\boxed{13.7}

So we know the length of hypotenuse and length of side a therefore side b can be calculated using Pythagorean theorem: c^2=a^2+b^2.

Solve for side b.

c^2=a^2+b^2

b=\sqrt{c^2-a^2}

b=\sqrt{13.7^2-9^2}\approx\boxed{9.7}

So there you go. If you have any questions feel free to ask.
