Answer:
x = 98
Step-by-step explanation:
The sum of the interior angles in a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7, thus
sum = 180° × 5 = 900°
Sum the interior angles and equate to 900
x + 146 + 122 + 142 + 140 + 110 + 142 = 900, that is
x + 802 = 900 ( subtract 802 from both sides )
x = 98
Step-by-step explanation:
7^2 × 3.14 × 2 + 3.14×14×672×3.14×2+3.14×14×6 = 49 × 6.28 + 3.14 × 8449×6.28+3.14×84 = 307.72+263.76307.72+263.76 = 571.48 cm^2c
Answer:
(√2+1 )(√2+3 )
(√2×√2)+(√2×3)+(1×√2)+(1×3)
2+3√2+√2+3 = 5+4√2
=5+4√2
