Answer:
m=-3
Step-by-step explanation:
10=7-m
m=7-10=-3
Answer:
8x^2 - 4x
Step-by-step explanation:
add like terms
Well, the first line has a slope of -3, and runs through 0, -1.
a line parallel to that one, will have the same exact slope of -3.
now, we know about this other parallel line that it runs through -3,1, and of course, since is parallel, it has a slope of -3
Answer:
X=66°
Step-by-step explanation:
Because it is an isosceles triangle, the 2 missing angles are going to be the same size.
Subtract 48 from the total degree of the triangle which is 180.
180-48= 132
now you di ed that by 2 and you’ll know the missing angle.
132/2= 66
Step-by-step explanation:
A regular n-sided polygon has n axes of symmetry. The angle between two consecutive axes is 360° / n.
In the case of an octagon, the angle is 360° / 8 = 45°.
