Answer:

Acute scalene triangle.

Sides: a = 6   b = 8   c = 9

Area: T = 23.525

Perimeter: p = 23

Semiperimeter: s = 11.5

Angle ∠ A = α = 40.804° = 40°48'16″ = 0.712 rad

Angle ∠ B = β = 60.611° = 60°36'39″ = 1.058 rad

Angle ∠ C = γ = 78.585° = 78°35'5″ = 1.372 rad

Height: ha = 7.842

Height: hb = 5.881

Height: hc = 5.228

Median: ma = 7.969

Median: mb = 6.519

Median: mc = 5.454

Inradius: r = 2.046

Circumradius: R = 4.591

Vertex coordinates: A[9; 0] B[0; 0] C[2.944; 5.228]

Centroid: CG[3.981; 1.743]

Coordinates of the circumscribed circle: U[4.5; 0.909]

Coordinates of the inscribed circle: I[3.5; 2.046]

Exterior(or external, outer) angles of the triangle:  

∠ A' = α' = 139.196° = 139°11'44″ = 0.712 rad

∠ B' = β' = 119.389° = 119°23'21″ = 1.058 rad

∠ C' = γ' = 101.415° = 101°24'55″ = 1.372 rad

Hope This Helps!     Have A Nice Day!!

Sean read 15 of a book in 112 hours.
makvit [3.9K]
Sean read 15 of a book in = 112 hours, 
so, 1 of a book in = 112/15

Now, 12 of a book would be: 112/15 * 12 = 112/5 * 4 = 89.6

89.6 = 89 6/10 = 89 3/5

In short, Your Answer would be 89 3/5 hours

Hope this helps!

Please help me this is due today
Serjik [45]

Answer:

1. 15 (A)

2. 12 (G)

Step-by-step explanation:

1.  We can make an equation out of this...

    3x+3=48

    x is the age of Geoff which is what we are trying to find out

   

    We have to add 3 to both sides of the equation

    3x+3=48

         -3   -3

     ________

    we end up with 3x=45

     we then have to divide 3 by both sides because its the opposite of                

     multipling

    3x=45

    _____

         3

    we get x=15

2.   We can write a problem statement  

      (2 x 9)-6=?

       multiply 2 and 9 <u>FIRST</u>

     

       18-6=?

       your answer is 12

      Your Welcome! Have a great rest of your day! :)
