Answer:
a) Angle XBC = 55 because XY is parallel with BD
b) As given, XB = XC, so that triangle XBC is the equilateral triangle.
As XBC is equilateral triangle, angle XBC is equal to angle XCB
Angle XBC = 55° => Angle XCB = 55°
In a triangle, the total value of three corners are equal to 180°
So that: Angle XBC + Angle XCB + Angle BXC = 180°
=> 55° + 55° + Angle BXC = 180 °
=> Angle BXC = 70°
Answer:
40
Step-by-step explanation:
If you look at the ratios you can see the pattern of the first number being multiplied by 4 everytime. Therefore you must multiply 10 by 4.
Answer:
b squared minus 4ac describes the discriminant which means the amount of solutions that the equation will have.
Answer:
A. always
Step-by-step explanation:
we know that
Parallel lines are those lines which never intersect to each other and always have same distance between them
Two lines always have same distance will only be possible when they lie on same plane
and we know that
same plane means co-planar
so, two lines will be parallel only if they are co-planar
It means that
Parallel lines are always co-planar
So,
Answer is
A. always
$72.
20% of 60 is 12
$12 + $60 = $72
