Answer:
a) angle XBC=55° because corresponding angles are congruent.
b) <BXC=70°
Step-by-step explanation:
From the diagram, XY and BD are parallel lines.
This means line AB is a transversal .
Angle XBC and angle AXY form an F-angle.
F-angles are also called corresponding angles, and are congruent.
Therefore, angle XBC=55° because corresponding angles are congruent.
b) We want to work out, angle BXC.
Since XB=XC, triangle XBC is isosceles.
The base angles of an isosceles triangles are equal.
This implies that:
<XBC=<BCX=55°.
Also, sum of angles in a triangle add up to 180°.
<XBC+<BCX+<BXC=180°
55°+55°+<BXC=180°
<BXC=180°-55°-55°
<BXC=180°-110°
<BXC=70°
Answer: x = 3
Step-by-step explanation: 10 x + 20 = 5x + 35
10 x + 20 - 5x = 35
5x = 35 - 20
5x = 15
x = 3
Answer:
Step-by-step explanation:
x^2 - 9x - 70
we need to find two numbers whose sum is -9 and product id -17
The numbers are -14 and 5
By splitting the middle term,
x^2 - 14x + 5x - 70
= x ( x - 14 ) + 5 ( x - 14 )
( x + 5 ) ( x - 14 )
