Answer:
11.2 mm
Explanation:
Given a right angle triangle, In order to find the third side: Use Pythagoras Theorem: a² + b² = c²
Insert Values:
x² + 3.8² = 11.8²
x² + 14.44 = 139.24
x² = 139.24 - 14.44 (subtract)
x² = 124.8
x = √124.8 (square root)
x = 11.1714 ≈ 11.2 (rounded to 3 significant figures)
Answer:
<u>Solutions given;</u>
<u>Using cosine rule</u>
b²=a²+c²-2*a*c*cos B°
b²=15²+8²-2*15*8*cos39
b²=102.48
b=
b=10.12
b=10.1
<u>Using sine rule</u>
<u>Doing criss cross multiplication</u>
Sin C=
m<C=Sin -¹(0.29)
m<C=14.98
<u>m<C=15°</u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>answer</u><u>.</u>
Divide the discount by the price
7/25 = 28%
Answer:
150.72
Step-by-step explanation:
C = 2*pi * r
C = 2* 3.14 * 6
C = 37.68
1 revolution = 37.68
4 revolutions = 4 * 37.68
4 revolutions = 150.72
