Question: </h3><h3>
In the diagram below of Δ ABC, side BC is extended to point D, m∠A = x , m∠B = 2x+15, and m∠ACD = 5x+5 , what is m∠B ?</h3>
Answer: 3) m∠B = 25º
Step-by-step explanation:
Since m∠C is supplementary to m∠ACD
m∠C = 180º - m∠ACD
m∠C = 180º -(5·x + 5)
m∠C = 180º -5 -5·x
m∠C = 175º - 5·x
The sum of the angles of a triangle = 180º
m∠A + m∠B + m∠C = 180º
x + 2·x + 15º + 175º - 5·x = 180º
3·x - 5·x +190º = 180º
-2·x = 180º - 190º
-2·x = -10º
x = -10º/-2 = 5º
Now we can substitute this value of x in m∠B
m∠B = 2x+15
m∠B = 2·x + 15º = 2·5º + 15º = 10º + 15º = 25º
Answer: 3) m∠B = 25º

Answer:
Ratio of the volume of the triangular prism and the volume of cuboid = 3 : 20
Step-by-step explanation:
Volume of a triangular prism = Area of the triangular base × Height
=
× Height
=
× 9
= 90 cm³
Volume of the rectangular prism or cuboid = Length × Width × Height
= 6 × 5 × 20
= 600 cm³
Therefore, ratio of the volumes of triangular prism and cuboid = 
= 
= 3 : 20
