Can you please help me?

(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

r(0,90)(x,y) . t(-5,0)

last option

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

yes
