2a-5b

= 1/2

3a+2b

find a/b

a/b = 12

Step-by-step explanation:

2a -5b          1

=

3a+2b             2

We can use cross products to get in the form of a /b

2(2a-5b) = 1(3a+2b)

Distribute

4a -10b=3a+2b

Get the a terms on the left and the b terms on the right

Subtract 3a from each side

4a-3a -10b=3a-3a+2b

a - 10b = 2b

Add 10b to each side

a-10b +10b = 2b+10b

a = 12 b

Divide each side by b

a/b = 12b/b

a/b = 12

step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
