Answer:
21 packages
Step-by-step explanation:
We need to identify the area of the parallelogram. Given that:
- The base of 17.5 feet
- The height of 6 feet
=> S = bh = 17.5 x 6 = 105 ft²
Area covered by 1 package of tile = 5 ft²
So the number of packages of tile will be needed to tile the art closet floor:
The area of the parallelogram / Area covered by 1 package of tile
= 21 packages

Answer:
20 degrees
Step-by-step explanation:
First, draw the triangle and label the sides and angles. (See the picture attached)
The red lines on sides FG and HF indicate that the sides are congruent since this is an isosceles triangle. Isosceles triangles have two congruent sides and angles.
All angles add up to 180 degrees. You were already given 140 for angle F. So, use to find angle h, subtract 140 from 180 and divide by 2.
180 - 140 = 40
40 / 2 = 20
Angle h is 20 degrees
