Answer:

122°  

Step-by-step explanation:

The formula for finding the sum of all angles in a polygon is:

(n-2) * 180°

n is the number of angles

Here n = 7, so the sum of all angles is

(7-2) * 180°  = 900°

x = 900 - 128 - 130 - 120 - 115 - 145 - 140 = 122°

The perimeter of an isosceles trapezoid is 28 in and the ratio of lengths of its bases is 5:3. Find the lengths of the sides of
dalvyx [7]
We are given the
perimeter of isosceles trapezoid = 28 in
ratio of length of bases = 5:3

We are to find the lengths of sides of the trapezoid and the diagonal that bisects the angle at the base with a longer length

The formula for the perimeter of an isosceles trapezoid is
P = (1/2) (b1 + b2) h

We are given the ratio
b2/ b1 = 5 /3
b2 = 5/3 b1
Substituting
28 = (1/2) (5/3 b1) h
The height of the trapezoid is expressed in terms of b1
For the diagonal
d² = h² + [(b2 - b1) + (b2 - b1)/2]²
Express h and b2 in terms of b1 and diagonal can be expressed in terms of b1
