The sum of the measures of the angles of a triangle is 180 deg.
m<J + m<K + m<L = 180
72 + 36 + m<L = 180
m<L = 72

Both angles J and L measure 72 deg.
Angles J and L are base angles measuring 72 deg.
Angle K is the vertex angle measuring 36 deg.

We know that all triangles equal 180° 

To find the missing angle we do this,

∠J + ∠K + ∠L = 180

72° + 36° + ∠L = 180   SUBSTITUTION 

108 + ∠L = 180°

180 - 108 = ∠L Property of algebra (Opposite of plus)

∠L = 72°

if a quadratic equation with real coefficients has a discriminant of -36 then what type of roots does it have
Aleks04 [339]

Step-by-step explanation:

We have,

If a quadratic equation with real coefficients has a discriminant of -36.

The general form of quadratic equation is :

ax^2+bx+c=0

The discriminant of this equation is : D=b^2-4ac

If D=0, it will have 1 real roots

If D>0, it will have 2 real roots

If D<0, it will have no real roots

We have,

D = -36 < 0, so, the quadratic equation will have no real roots.

Answer:

The answer is 104

Step-by-step explanation:

I’m guessing the shape is a triangle so if you have to angels you add them up and minus then from 180 what you get is your missing angle.
