Answer:
yes they form a proportion
Answer:
w =< 70
(width is less or equal to 70 inches)
Step-by-step explanation:
Let l = length, w = width, h = height
Restrictions given in this question:
'sum of perimeter of the base and the height cannot exceed 130 inches'
perimeter of the base is 2 width and 2 length of the box
perimeter = 2w + 2l
Therefore, inequality involves here is
2w + 2l + h =< 130
(Note that =< here means less or equal)
Then a new condition given with
height, h = 60 in
and length is 2.5 times the width
l = 2.5w
Substitute this new condition into the equation will give us the following:
2w + 2(2.5w) + 60 =< 130
2w + 5w + 60 =< 130
7w + 60 =< 130
7w =< 130-60
7w =< 70
w =< 10

Answer:
70°
Step-by-step explanation:
We know that the triangle is an iscoceles based on the 2 small lines drawn horizontally on 2 sides of the triangle.
We know that the base angles in an iscoceles triangle are the same, so the angle that has not been drawn is 55°.
55° + 55° = 110°
180° - 110° = 70° (180 comes from the entire triangle adding up to 180°)
