URGENT Which Is A True Statement About Triangle ABC class=

Sagot :

Answer:

1st option

Step-by-step explanation:

In right triangle BCD

cosC = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{b-x}{a}[/tex] ( multiply both sides by a )

b - x = acosC ( subtract b from both sides )

- x = acosC - b ( multiply through by - 1 )

x = b - acosC
