Can someone help me with this circle graph.
Due today I need urgent help please.

a) 99

b) 20

c) 27

d) 126

Step-by-step explanation:

a) 18% of 550 = 99

b) 360 deg = 550 people

1 deg = 550/360 people

72 deg = 110 people

x% of 550 = 110

x = 20

c) %of speedy + 18 + 35 + 20 = 100

% of speedy = 27

d) 20% = 72deg

1% = 72/20 deg

35% = 72/20 * 35 deg = 126 deg

∠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.

y > 1/3x

y < = -x + 4

hope this : )
