Question

Given that answer please

Answer 1

Answer:

<BCA = 44.4°

Step-by-step explanation:

Reference angle = <BCA = C

Opposite side length = x = 7 cm

Hypotenuse = y = 10 cm

Applying trigonometric ratio, we would have:

$sin(C) = \frac{7}{10}$

$C = sin^{-1}(\frac{7}{10})$

$C = 44.427004$

<BCA = 44.4° (to 3 SF)
