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.

Which expression is equivalent to (4+3i)^2+(6-I)^2
zhenek [66]

Answer:

\large\boxed{(4+3i)^2+(6-i)^2=42+12i}

Step-by-step explanation:

(4+3i)^2+(6-i)^2\qquad\text{use}\ (a\pm b)^2=a^2\pm2ab+b^2\\\\=4^2+2(4)(3i)+(3i)^2+6^2-2(6)(i)+i^2\\\\=16+24i+9i^2+36-12i+i^2\qquad i=\sqrt{-1}\to i^2=-1\\\\=16+24i+9(-1)+36-12i+(-1)\\\\=16+24i-9+36-12i-1\qquad\text{combine like terms}\\\\=(16-9+36-1)+(24i-12i)\\\\=42+12i
