Answer:
see explanation
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan A =
=
=
, then
∠ A =
(
) ≈ 41° ( to the nearest degree )
The sum of the angles in the triangle = 180° , then
∠ B + 41° + 90° = 180°
∠ B + 131° = 180° ( subtract 131° from both sides )
∠ B = 49°
Using Pythagoras' identity in the right triangle
AB² = BC² + AC² = 7² + 8² = 49 + 64 = 113 ( take square root of both sides )
AB =
≈ 10.6 ( to the nearest tenth )
Quotient: The answer to a division problem
Answer:
30 meters
Step-by-step explanation:
You MUST multiply 5 and 6 to get 30 to find area you have to multiply length times width
Subtract 6 from both sides, you get 1/3x=-14
Now multiply both sides by there, hence x=-42
