Answer:
see details and attached figure below.
Step-by-step explanation:
Going row by row
1. 12 (isosceles triangles have equal legs from the vertex)
2. 55 deg. (isosceles triangles have equal base angles)
3. 90 = 180-45-45 (isosceles triangles have equal base angles)
4. 2x-8 = 10
=> x = 18/2 = 9 (isosceles triangles have equal legs from the vertex)
5. sum of angles of triangle = 180
3x+3x+2x+4 = 180 => 8x = 176, x = 22, angle A = 3x = 66 deg.
6. sum of angles of triangle = 180
(isosceles triangles have equal base angles)
25+25+angle Z = 180 => angle Z = 180-25-25 = 130
Answer:
2/3 feet.
Step-by-step explanation:
We have to calculate the length of the base of the triangle, in this case they give us the area of the triangle but still it is necessary to know the height of the triangle to calculate the length of the base, otherwise it would be impossible.
I have found an image where the graph is, which I will attach where you can see that the height is 6/5 ft. The area of the triangle is:
A = b * h / 2
solved for b which is the length of the base of the triangle would be:
b = 2 * A / h
replacing:
b = 2 * (2/5) / (6/5)
b = 20/30
b = 2/3
Which means that the length of the base of that triangle is 2/3 feet.
