I just did this is class the answer is 23=p.250 then do p.250 over 250 cross that the do 23 over 250 so divide 23 by 250 you will get 0.092 move the decimal point two times over you will get 9.2 round that up to the nearest whole number and you will get 9 so 9 percent :)

5. Solve the following triangle for all missing sides and angles.

Ipatiy [6.2K]

Answer:

Part I : 100°

Part II : a = 29.2

Part III : b = 20.95

Step-by-step explanation:

See the attached diagram of the triangle.

Part I: ∠ A = 180° - ∠ B - ∠ C = 180° - 45° - 35° = 100°

Part II: Now, applying the law of sines, we have

$\frac{AB}{\sin 35^\circ} = \frac{BC}{\sin 100^\circ}$

⇒ $\frac{17}{\sin 35^\circ} = \frac{a}{\sin 100^\circ}$

⇒ $a = \frac{17}{\sin 35^\circ} \times \sin 100^\circ$

⇒ a = 29.2 (Answer)

Part III: Now, applying law of cosine, we have

b = a cos 35° + c cos 100° = 29.2 cos 35° + 17 cos 100° = 20.95 (Answer)

If T is the midpoint of SU find the values of x and ST .

emmainna [20.7K]

Answer:

B

Step-by-step explanation:

Since T is at the midpoint of SU, then

ST = TU , substitute values

8x = 3x + 20 ( subtract 3x from both sides )

5x = 20 ( divide both sides by 5 )

x = 4

Thus

ST = 8x = 8(4) = 32
