The longest side of  a triangle must be less than the sum of the other 2 sides

2 senarios

the 3rd side is the longest
the 3rd side is not the longest



for the 3rd side is the longest

3rdside<28+42
3rdside<70


for 3rd side isn't the longest
42 is longest
42<28+3rdside
14<3rdside

so we've got
3rdside<70 and 14<3rdside

so
14<3rdside<70

the 3rd side can be any number from 14in to 70in except 14in and 70in

Hole volume = lbh

= 2*3*12

= 72cm^3

What is a equation in slope intercept form for the line that has a slope -1 that passes through (-4,3)
aleksley [76]

slope is -1

m=-1

we have a point as (-4,3)

we can use slope intercept form of line

y=mx+b

we can plug m=-1

y=-x+b

now, we can plug point (-4,3)

x=-4 and y=3 and then we can find b

3=-1*-4+b

b=-1

now, we can plug back

and we get

y=-x-1............Answer

The angles in a triangle add up to 180 degrees.  That's the same sum as a linear pair, which we get when two lines cross.

1. 180 - 65 - 45 = 70

Answer: 70°

2. 180 - 90 - 35 = 55

Answer: 55°

3. 180 - 120 = 180 - 50 - x

x = 70

Answer: 70°
