Answer:
False
Step-by-step explanation:
165 - 90 = 75 + 40 = 115
115 is not the same as 165
Answer:
x = 6
Step-by-step explanation:
180° is always all triangles.
This is a right triangle, so that means that the angle that is unknown is 90.
Angles:
90
60
7x - 12
90 + 60 + 7x - 12 = 180
150 - 12 + 7x = 180
138 + 7x = 180
7x = 180 - 138
7x = 42
7x/7 = 42/7
x = 6
Answer:
1,2,3,6
Step-by-step explanation:
The triangle has a two acute angles so it definitely isnt acute,(true)
It has a obtuse angle so it is obtuse.(true)
It's two angles are same.Thus,it is an isosceles triangle.(true)
Not all it's angle are different so not scalene(false)
Not all its angle are equal so not equilatera(false)
All triangles add up to 180 and this one does too.(true)
Answer:
x= -6
Step-by-step explanation:
Notice that a(-6,7) and b(-6,-3) have the same x-coordinate (-6). This means that x is constant and that the line is a vertical one (x = -6).
The equation of the line through these two points is x = -6.
I would say it’s C because you make X negative
