Answer:
- When Three sides of the triangle are known
- Two sides of the triangle is known and corresponding angle is included
- Two angles known and their included side given
- Two angles known and the length of a non included side is given
Step-by-step explanation:
The measure that will determine a unique triangle are
- when Three sides of the triangle are known
- Two sides of the triangle is known and their corresponding angle is included
- Two angles known and their included side given
- Two angles known and the length of a non included side is given
unique triangles are termed unique because they can be drawn only using one way
I believe the answer is they are drawing an Octagon because a polygon has 5 sides add that by three it's an Octagon
Answer:
- 5.8206 cm
- 10.528 cm
- 23.056 cm^2
Step-by-step explanation:
(a) The Law of Sines can be used to find BD.
BD/sin(48°) = BD/sin(50°)
BD = (6 cm)(sin(48°)/sin(60°)) ≈ 5.82064 cm
__
(b) We can use the Law of Cosines to find AD.
AD^2 = AB^2 +BD^2 -2·AB·BD·cos(98°) . . . . . angle ABD = 48°+50°
AD^2 ≈ 110.841
AD ≈ √110.841 ≈ 10.5281 . . . cm
__
(c) The area of ∆ABD can be found using the formula ...
A = ab·sin(θ)/2 . . . . . where a=AB, b=BD, θ = 98°
A = (8 cm)(5.82064 cm)sin(98°)/2 ≈ 23.0560 cm^2
_____
Angle ABD is the external angle of ∆BCD that is the sum of the remote interior angles BCD and BDC. Hence ∠ABD = 48° +50° = 98°.
Answer:8 cars
Step-by-step explanation:
to find the least amount of cars dived 30/4 which equilds 7.5
Since there are 2 remaining students, an additional car will be needed bringing the total to 8 cars.
Answer:
