Answer: B. 431.59
Step-by-step explanation:
1.6*12 =19
90*2 = 180
circle area = pier^2
127.25 for upper and 88.35 for lower
triangle is just the square / 2
i rounded so my answer is not exact but b should be correct
-3 (5 - x) = 4x
-15 + x = 4x
-15 = 3x
X = 5
a^2 + b^2 = c^2 is right a^2 + b^2 > c^2 is acute a^2 + b^2 < c^2 is obtuse
a^2 + b^2 = c^2
18^2 + 23^2 = 30^2
324 + 529 = 900
853 < 900
obtuse
