Find the area of triangle ABC

A ≈ 31.7 cm²

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = × AC × BC × sinC

∠ C = 180° - 72° - 59° = 180° - 131° = 49° , then

A = × 7 × 12 × sin49°

   = × 84 × sin49°

   = 42 × sin49°

   ≈ 31.7 cm² ( to 1 dec. place )

depends on how many days you are talking about

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
