4 is a obtuse isosceles  

2 is a scalene obtuse  

the rest are acute scalenes  

and i don't know how to do the second page

Step-by-step explanation:

All triangles angles combined are 180 degrees so to figure out a missing angle subtact the present angles from 180

if there's a small square the angle is 90 degrees

and

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

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
