Answer:
? = 85°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5 , then
sum = 180° × 3 = 540°
sum of the angles around a point = 360° , so
interior angle on right = 360° - 250° = 110°
sum the interior angles and equate to 540°
110° + 115° + 120° + 110° + ? = 540° , that is
455° + ? = 540° ( subtract 455° from both sides )
? = 85°
Answer:
x = ± 
It didn't insert but just look up the quadratic formula.
x = ± root [(b²-4ac]/2a]
Answer:
m = 48
Step-by-step explanation:
6=m/8
Multiply each side by 8
6*8 = m/8 *8
48 = m
Multiply 0.57 by 51
=29.07
