Question

The diagram shows a right-angled triangle,
Calculate the value of x.

Answer 1

Answer:

x = 12

Step-by-step explanation:

$90 + 3x + 16 + 2x + 14 = 180$

$5x + 120 = 180$

$5x = 180 - 120$

$5x = 60$

$x = \frac{60}{5} = 12$

Answer 2

Answer:

x = 12°

Step-by-step explanation:

$(3x + 16) + 90 + (2x + 14) = 180 \\ 3x + 2x = 180 - 16 - 90 - 14 \\ 5x = 60 \\ x = \frac{60}{5} \\ x = 12$
