I8,000 I hope I could help! Now ace that assignment!
Answer:
2880
Step-by-step explanation:
The base is made up of two triangles and a square, if that makes sense. Finding the area of a triangle is (base x height)/2.
The base of the tiny triangle is 4 because there is 8 inches extra to the 10 inch square. <u>10 x 4 = 40.</u>
Now we have a 10 by 10 square: <u>10 x 10 = 100. </u>
So, the area of the trapezoid is 140. There are two trapezoids in this prism, so both bases are 280.
The surface area of the sides are solved by <u>12 x 50 = 600. </u>Together, the sides equal 1200.
The top is solved by <u>10 x 50 = 500.</u>
The bottom is solved by <u>18 x 50 = 900.</u>
Add them all together: 280 + 1200 + 500 + 900 = 2,880
2x-2x+4=6
4=6
and since there's no such things im gonna say D.no solution
Answer:
D
Step-by-step explanation:
Using sine rule
a/sin A ＝b/sin B
8/sin90° ＝ x/sin60°
8 * sin60° ＝ x
x ＝
