Can you anser number 9

Step-by-step explanation:

Equations

Let's call

x = measure of angle 1

y = measure of angle 2

The angles are supplementary, thus their sum is 180°:

x + y = 180        [1]

It's also known that one angle (x) is 7° more than twice the other (y), thus:

x = 7+ 2y        [2]

Substituting [2} in [1]:

7+ 2y + y = 180

Operating:

7+ 3y = 180

Subtracting 7:

3y = 180 - 7 = 173

Dividing by 3:

And:

∠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.
