The answer of t he trapezoid area problem is 112.
Answer:
72
Step-by-step explanation:
Answer:
168 cm³
Step-by-step explanation:
The base of the prism is a right triangle whose hypotenuse is 10 cm and one other side is 6 cm.
So, the third side of the triangle = 
cm.
{Since we have applied the Pythagoras theorem.}
Hence, the area of the base triangle is 
cm².
Therefore, the volume of the prism is = 
cm³ {Since volume of a prism is given by ( Area of the base triangle ) × ( Height of the prism )}

Answer:
m<A = 120°
m<C = 45°
Step-by-step explanation:
We can use the triangle sum theorem to find the measures of the angles.
m<A + m<B + m<C = 180°
Then substitute in their given values.
12x + 12 + 15 + 3x + 18 = 180°
Now simplify the equation and you get
15x + 45 = 180°
Continue to solve
15x = 135
x = 9°
Now substitute this value of 9 for the angle expressions of <A and <C
(12 x 9) +12 = m<A
m<A = 120°
(3 x 9)+ 18 = m<C
m<C = 45°
Hope this helps. To check your answer you can add up all the answers to see if it equals 180°.
