What is the length of AC¯¯¯¯¯ ?

Harman [31]

Answer:

AC = 12.38 cm

Step-by-step explanation:

When there are 2 pairs given, we can use the sine rule to solve the problem.

By pairs we mean "an angle and side opposite to it"

1 pair is 85.2 degree angle and 13 cm, and another pair is 71.6 degree angle and the side AC (which we want to figure out).

Sine Rule is given by $\frac{SinA}{a}=\frac{SinB}{b}$

where,

A and B are the two respective angles and a and b are the two respective sides (of the pairs). Plugging all the info and using algebra, we have:

$\frac{Sin85.2}{13}=\frac{Sin71.6}{AC}\\AC*Sin85.2=13*Sin71.6\\AC=\frac{13*Sin71.6}{Sin85.2}\\AC=12.38$

Thus, AC = 12.38 cm

Solve the expression 94-x-67-x

Leni [432]

I guess it is simplifying the expression:

${ \tt{94 - x - 67 - x}} \\ = { \tt{94 - 67 + ( - x - x)}} \\ = { \tt{27 - (x + x)}} \\ = { \tt{27 - 2x}}$
