Use the given information to solve the triangle for A = 150°, b = 4.8, a = 9.4
ELEN [110]
Well you can start by drawing a triangle with the information 

the size of angle B can be found using the Law of Sine

\frac{sin(150)}{9.4)}  =  \frac{sin(B)}{4.8}

the size of angle C can be found using angle sum of a triangle. 

The length of side c can be found using the Law of Cosines

c^2 = 4.8^2 + 9.4^2 - 2 \times4.8\times9.4\times  cos(C)

hope it helps

Answer:

  B

Step-by-step explanation:

Given the triangle congruence statements, the segment and angle congruence statements must refer to corresponding vertices. Corresponding vertices are listed in the same order in the triangle congruence statement.

The one FALSE statement in the bunch is ...

  \overline{OD}\cong\overline{AL}

__

The true statements for these segments would be ...

  \overline{OD}\cong\overline{JL}\\\\\overline{CD}\cong\overline{AL}

If 2a-b:2a+b=1:2find the value of a:b​
weqwewe [10]

Answer & Step-by-step explanation:

2a - b : 2a + b = 1 : 2

2a - b = 1

-                         Elimination

2a + b = 2

-b - (b) = -1

-2b = -1

b = 0.5

---------------------------------------------------------------------------------

2a + b = 2           Substitution

2a + 0.5 = 2

2a = 1.5

a = 0.75

--------------------------------------------------------------------------------------

a:b

0.75 : 0.5

or

3/4 : 1/2

Hope this helps!!!
