Answer:

1. x = 11.5

2. x = 14.35

Step-by-step explanation:

[tex]1. \: sin(angleBAC) = \frac{BC}{AB} [/tex]

[tex]sin(35°) = \frac{x}{20} [/tex]

x = 11.472 ≈ 11.5

[tex]2. \: tan(angleBAC) = \frac{BC}{AB} [/tex]

[tex]tan(64°) = \frac{x}{7} [/tex]

x = 14.352 ≈ 14.35

HOPE THIS HELPS AND HAVE A NICE DAY <3
