the sum of the interior angles is 180° (triangles)
it's isosceles, 2 equal sides and 2 equal angles.
you take away the given angle from 360° and you will find the sum of the 2 equal sides, you divide by 2 and you have the angle b (equal to angle C).
(180 - 72) : 2 =
108 : 2 = 54° (your answer)
-----------------------
72 + 54 + 54 = 180°
The answer is good.
Answer:
512 cm3
Step-by-step explanation:
( √5 + √7 )( √20 + √3 )
= (2.23 + 2.64)( 4.47 + 1.73)
= 4.87 × 6.2
= 30.194
