Answer:
47.5
Step-by-step explanation:
x = 32°
The triangle has 2 equal sides and is therefore isosceles, thus the 2 base angles are also congruent.
The 2 base angles are of size x°
x = 
= 
= 32
Answer:point form= (-10,16)
Equation form : x=-10,y=16
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
The polygon given has 6 sides
Sum of interior angles of a 6-sided polygon = 180(n - 2)
substitute n = 6 into 180(n - 2)
Sum of the polygon = 180(6 - 2) = 720°
Thus:
10x + 8x - 16 + 12x - 8 + 7x + 2 + 9x + 4 + 6x + 10 = 720
Add like terms
52x - 8 = 720
52x = 720 + 8
52x = 728
x = 728/52
x = 14
