Find the number of degrees in

110º

Step-by-step explanation:

The two given angles are co-interior angles, and add up to 180º.

So, set up an equation.

3x+4  +  5x   = 180

8x = 176

x = 22

Now, angle D is also cointerior to angle C, meaning THEY add up to 180 as well.

D + 3x+4 = 180

sub x=22

D + 3(22)+4 = 180

D = 180 - 70

D = 110

26

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.
