Answer:
36
Step-by-step explanation:
Angles in a triangle sum to 180 degrees.
The angle in the bottom left will equal 180 - (3x + 6) as angles along a staight line also sum to 180 degrees.
180 - ( 3x + 6)
180 - 3x - 6 [expand bracket]
174 - 3x
Now we can add up all the angles and equate them to 180 to solve for x.
24 + 2x + 18 + 174 - 3x = 180
216 - x = 180
216 = 180 + x
x = 36
Answer:
x=4+y
Step-by-step explanation:
we are given that
Michelle plotted 3 points from the equation y = 6 on this coordinate grid
It means that y-value will be 6 irrespective of any value of x
for exp: (1,6) (2,6) (3,6) ...
so, y-value must be fixed as 6
and x-value can be anything
so, we can see that the only point which has y-value =6 is (+4, +6)
so,
option-C........Answer
Answer:
it is 30.5
Step-by-step explanation:
(3X+4Y):2
(3×7+4×10):2
(21+40):2
61:2
30.5
(1) it can be both exterior of vertex or base. 180-130=50°
vertex is 50°: base=(180-50)/2=65°
base is 50°: vertex= 180-2*50=80°
vertex 50 base 65; vertex 80, base 50
(2)base=180-130=50°
vertex=180-2*50=80°
base 50 vertex 80
