(3) z = 99°

(4) thirty thousand, six hundred and eighty-two

Step-by-step explanation:

(3) From the diagram,

Since the triangle is an issoceles triangle, The angle of the base are equal.

Applying

180° = x+x+18 (sum of angle in a triangle)

Where x = angle of each base of the triangle

180° = 2x+18

2x = 180-18

2x = 162

x = 162/2

x = 81°

But

x+z = 180 (sum of the angle in a straight line)

z = 180-x

z = 180-81

z = 99°

(4) 30682 in words =  thirty thousand, six hundred and eighty-two

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
