Im bad at angles pls help lol

n<DEH =

Exact form:

x = 29/2

Decimal form:

x = 14.5

Mixed number form:

x = 14 1/2

Total:

(12x+6) = 180

n<HEG =

Exact form:

x = 179/7

Decimal form:

x = 25.57142857

Mixed number form:

x = 25 4/7

Total:

(7x+1) = 180

n<GEF =

Exact form:

x = 91/3

Decimal form:

x = 30.3

Mixed number form:

x = 30 1/3

Total:

(6x-2) = 180

DEH:; 90.  HEG, 50.  GEF:;  40.

Step-by-step explanation:

x = 7

DEH. (12x + 6)

(12 x 7) + 6 = 90.

HEG. (7x + 1)

(7 x 7) + 1 = 50.

GEF. (6x - 2)

(6 x 7) - 2 = 40

Hope this helps!

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
