Answer:
8) 52
9) 52
10) 52
11) 128
12) 128
Step-by-step explanation:
8) <2 = <6 because of corresponding angles
9) <2 = <7 because of alternate exterior angles
10) <2 = <3 because of vertical angles
11) Supplementary angles
<5 = x
x + 52 = 180
x = 128
12) Supplementary angles
<4 = x
x + 52 = 180
x = 128
Answer:
H=12
Step-by-step explanation:
Khan said so
X= 8
y= 8root2

The number is 63, so the quotient is 2.
Two digit numbers divisible by 21:
21, 42, 63, 84
21: 2-1 = 1 * 3.5 = 3.5
3.5*2*1 = 7 but 7 does not equal 21
42: 4-2 = 2 * 3.5 = 7
3.5*4*2 = 28 does not equal 42
63: 6-3 = 3*3.5 = 13.5
3.5*6*3 = 63 :)
Check:
21(6-3)=21(3)= 63 :)
3.5(6)(3) = 21(3) = 63 :)
63: 6/3 = 2
