Someimes becasue either x or y could be obtuse.
Answer:
y = 51.3°
Step-by-step explanation:
tan(y) = Opp./Adj
tan(y) = 10/8
tan(y) = 1.25
y = 51.3°
Answer:
120 m^2
Step-by-step explanation:
6*2=12 for each narrow piece of the rectangular prism and since there are four multiply 12 times 4. Use the equation 6*6=36 for each of the larger sides and multiply 36 by 2 because there are only two large sides.
Given:
Angle A = 18.6°
Angle B = 93°
Length of side AB = 646 meters
To find:
the distance across the river, distance between BC
Steps:
Since we know the measure of 2 angles of a triangle we can find the measure of the third angle.
18.6° + 93° + ∠C = 180°
111.6° + ∠C = 180°
∠C = 180° - 111.6°
∠C = 68.4°
Therefore the measure of angle C is 68.4°.
now we can use the law of Sines,
meters
Therefore, the distance across the river is 222 meters.
