The third side must be >2 and < 18
To test if a triangle is acute, right or obtuse:
1) Square all 3 sides
2) Sum the squares of the 2 shortest sides
3) Compare this sum to side 3 squared
if sum > side 3 squared it is an acute triangle
if sum = side 3 squared it is a right triangle
if sum < side 3 squared it is an obtuse triangle
The shortest side 2 can be is "less than 2" so we'll say it is 2.00000001
three sides squared =

4.00000004

64
100
Summing the 2 shortest sides 4.00000004 + 64 = <span>68.00000004
</span><span>68.00000004 is less than 100 so it is an obtuse triangle no matter how long the third side is.

Answer:
A=30
Step-by-step explanation:
Set your equation up as following:
180=90+(x+37)+(x+67)
180=90+37+67+2x
180-90-37-67=2x
-14=2x
-14/2=x
-7=x
Angle A = x+37
A=-7+37
A=30
Answer: The customer should buy Giana’s jewelry box.
Step-by-step explanation:
The jewelry boxes are rectangular prisms, in order to find the box that would hold the most amount of jewelry we need to find the volumes of each box.
V= l.w.h
Katherine’s box: 5x5x5= 125
Giana’s box: 10x12x2= 240
Jackson’s box: 10x5x4= 200
Answer:
131 remaining after 72 days
Step-by-step explanation:
Answer:
y= -5
Step-by-step explanation:
x=0 is a vertical graph hence the perpendicular graph would be a horizontal line, a y= ____ graph.
Since it passes through the point (-2, -5),
the equation of the line is y= -5.
This would be in slope- intercept form since the gradient of horizontal lines is zero.
y= mx +c, where m is the gradient and c is the y-intercept.
Given that gradient =0, m=0
y= 0x +c
when x= -2, y= -5,
-5= 0(-2) +c
-5= c
c= -5
Thus the equation is y= -5.
