Answer:
-4
Step-by-step explanation:
Add 35+ 72.5=107.5 that should give you your answer for c and the answer for d is acute because the triangle would have to be 360 to be Obtused and it's not a right triangle because you don't have a 90 degree angle
The slope-point formula:

We have (0, 3) and (-10, 4)
Substitute:

Answer:
Those are the same measurment!
Step-by-step explanation:
Conversion:
Conversion is 1cm=10mm
Answer:
27in
Step-by-step explanation:
So, perimeter means we add all the sides together, as opposed to area, where we multiply them together.
9 - 5 = 4.
So the perimeter of the triangle would be:
3+4+
=12
5 + 5 + 4 +1 (the 1 is from 4 -3) = 15
15 + 12 = 27
