Answer:
angle 1 should equal to 54.
angle 2 should equal to 126.
Step-by-step explanation:
2x - 8 + 4x + 2 = 180
2x + 4x - 8 + 2 = 180
6x - 6 = 180
6x - 6 + 6 = 180 + 6
6x = 186
6x ÷ 6 = 186 ÷ 6
x = 31
---------------------------------------------
2x - 8 = A1
2(31) - 8 = A1
62 - 8 = A1
54 = A1
-----------------------------------------------
4x + 2 = A2
4(31) + 2 = A2
124 + 2 = A2
126 = A2
Step-by-step explanation:
IGH = JKL
GH = KL
12 = 36
12 × x = 36
x = 36 ÷ 12 = 3
IG =
= 20
y = 16 × 3 = 48
x =
= 60
There are two ways to find the total with tax
Either you can do
cost + cost x tax rate
or
cost x (1+tax rate)
Since the second one requires less steps, it's easier to do that.
The cost with tax is
$17.27
Answer:
4 hours
Step-by-step explanation:
55h = 80 + 35h
55h - 35h = 80 + 35h - 35h
20h = 80
20h/20 = 80/20
h = 4
Subsitute 9 for y
9=y=9x-9
add 9 to both sides
9+9=9x+9-9
18=9x+0
18=9x
divide by 9
2=x
y=9
x=2
