so in conclusion it is 28
Im not really sure but i thinki think it is
Answer:
98.88 ft^2 to nearest hundredth
Step-by-step explanation:
Area of slice = (37/360) * pi * 17.5^2 ( 17.5 = radius ( half diameter of 35))
= 98.88 ft^2
Answer:
14
Step-by-step explanation:
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 )
