Answer:
Step-by-step explanation:
∠XBC = 55°
XB = XC. So, ΔXBC is an isosceles triangle
∠XCB = ∠XBC
∠XCB = 55°
In ΔXBC,
∠BXC + ∠XBC + ∠XCB = 180 {Angle sum property of triangle}
∠BXC +55 +55 = 180
∠BXC + 110 = 180
∠BXC = 180 -110
∠BXC = 70°
Answer:
Step-by-step explanation:
Solution:
AM =( X_1 + X_2 )/2
=( 18 + 2 )/2
=20/2
=10
Find Geometric mean for data 18,2
Solution:
GM =sqrt( X_1 × X_2 )
=sqrt( 18 × 2 )
=sqrt(36)
=6
Similar objects can look the same, but be different sizes, while congruent objects are the exact same shape, size, etc. With congruent shapes, if you were to lay one ontop of the other, one would perfectly cover the other.
Hi!
18.49 * 5.75% = 1.063175
18.49 + 1.063175 = 19.553175 (Round to the nearest cent).
