Answer:
Yes that is correct
Step-by-step explanation:
56+56+68 = 180
Answer:
A and E
Step-by-step explanation:
A = 2.3
B = 1.64
C = 10.08
D = 2.71
E = 2.3
F = 10.08
Yes, If it were thAn, then it would be replacing. But in this case with that example, It means the green marble was added with the orange marble
Let the arc is ABC with angle 324 degree, to find the length of that arc follow the steps;
The circumference of the circle E is :C = 2 r π
C = 2 * 40 π = 80 π cm.
Also 324° / 360° = 0.9m Arc (ABC ) = 0.9 * 80 π = 72 π cm
There is also formula for calculating the measure of an arc:
m Arc = r π α / 180°
m Arc = 40 π * 324 / 180
= 40π * 1.8 = 72 π
Now we have to find the exact length ( π ≈ 3.14 )
m Arc ( ABC ) = 72 * 3.14 = 226.08 cm
Triangle A:
y = 57.5°
x = 57.5°
Triangle B:
y = 5
x = 6.5
Triangle C:
... I apologize but I do not know what Triangle C is. Sorry!!
Triangle D:
z = 30°
x = 90°
(x+20) = 110°
SORRY THAT TOOK SO LONG--
