Answer:
Step-by-step explanation:
Multiply 6 and 15 then you get 90 the you do 6x6 you get 36
After you subtract 90 from 36 = 54
C = 11.6239mm
Circumference Formula is C = 2πr
R = 1/2 D
R = radius
D = diameter
π = 3.14
C = circumference
1/2 3.7 = 1.85
2 x 3.14 x 1.85 = 11.6239
Using the law of Cosine:
Cos(angle) = Adjacent Leg / Hypotenuse
Cos(65) = x / 81.9
x = 81.9 x cos(65)
x = 34.61
The answer is A.
Answer:
Step-by-step explanation:
32a²b² = 2 * 2*2*2*2 * a² * b²
36a²c² = 2 * 2 * 3 * 3 * a² * c²
16ab³ = 2 * 2 * 2* 2 * a * b³
Greatest common factor = 2*2*a = 4a
32a²b² + 36a²c² - 16ab³ = 4a*(8ab² + 9ac² - 4b³)
Answer:
BCDE is inscribed quadrilateral. the opposite angles of a quadrilateral add up to 180°
<E = 84-180= 96°
ans is 96°
