The question is below

see explanation

Step-by-step explanation:

b = 79° ← corresponding angles are congruent

c = 83° ← vertical angles are congruent

a and b and c and d are same side interior angles and are supplementary, thus

a = 180° - b = 180° - 79° = 101°

d = 180° - c = 180° - 83° = 97°

Thus

a = 101°, b = 79°, c = 83°, d = 97°

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
