Given the triangle below, find the length of XW . Round your answer to the nearest tenth.

Ghella [55]

Check the picture below.

so let's use the law of sines then

$\textit{Law of sines} \\\\ \cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{1.9}{sin(Z)}~~ = ~~\cfrac{XZ}{sin(Y)}\implies \cfrac{1.9}{sin(89^o)}~~ = ~~\cfrac{XZ}{sin(70^o)}\implies \cfrac{1.9\cdot sin(70^o)}{sin(89^o)}=XZ \\\\[-0.35em] ~\dotfill$

$cos(21^o)=\cfrac{\stackrel{adjacent}{XW}}{\underset{hypotenuse}{XZ}}\implies XZ\cdot cos(21^o)=XW \\\\\\ \cfrac{1.9\cdot sin(70^o)\cdot cos(21^o)}{sin(89^o)}=XW\implies 1.7\approx XW$

quick observation, the picture of the triangle is very misleading, since those angles as drawn are not good representers of the angles values.

729-243=486

486×3=1458

1458+729=2187(x=7)

1458×3=4374

4374+2187=6561(x=8)

4374×3=13122(average rate of change for interval 8 to 9)

13122+6561=19683(x=9)

Consider the points A (45, 29), B (9,- 7) and C (5. – 11) Find the slope of AB.

Papessa [141]

The slope is 1. if you do y^2-y^1/x^2-x^1 you will get -36/-36 which simplified is 1.
