Two supplementary angles are in ratio.5 4 find the angles .

The angles are 80 and 100.

Step-by-step explanation:

Total angles for a supplementary angle is 180°.

Since the angles are in 5:4

5/9 × 180= 100

4/9 × 180= 80

The angles are 100° and 80°.

Step-by-step explanation:

Given,

Two supplementary angles are in ratio 5:4

To find the value of each angle.

Let,

Two angles are 5x and 4x.

For supplementary angle sum of two angles is 180°

So,

5x+4x = 180°

or, 9x= 180°

or, x = 180÷9

or, x = 20°

The angles are 100° and 80°.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
