Answer:
118°
Step-by-step explanation:
EDC is 31° and ECD has the same measure. (Triangle DEC is isosceles)
The total sum of angle EDC and ECD is 31 + 31 = 62°
The total sum of all the angle measures in a triangle is 180°, so just subtract 62 from 180 to get the measure of angle DEC.
180 - 62 = 118°

0 , 1 or infinitely many solutions
Step-by-step explanation:
Answer:
35 in²
Step-by-step explanation:
The irregular shaped can be divided into two squares and one rectangle, so the area will be the additions of the area of the squares and the rectangle
area of square A = L *B = 3 *3 = 9in²
area of square B = L * B = 4*4 = 16in²
area of rectangle C = L * B = 5 *2 = 10in²
th area of the irregular shape = 9 in² + 16 in² + 10 in² = 35 in²
Answer:
The slope is 0

Answer:
Step-by-step explanation:
Find the diagram attached.
The volume of a triangular prism = 
Since the base is a triangle, Base area = 1/2 * base * height
given base of the triangular base = 8in
height of the triangle = 9in
Base area = 1/2 * 8 * 9
Base area = 4*9
Base area = 36in²
Height of the prism = 10in
Volume of the prism = 
Volume of the prism = 
Volume of the prism =
