Answer:
a = 42 b = 21
Step-by-step explanation:
a is 42 since it ks vertically opposite 42
To solve for b
360 - (42×2)........to get the angle next to a
=276... Divde answer by 2. Bc there are two of the angles
276÷2 =138
138 + 2b =180
2b = 180 - 138
b = 42 ÷ 2
b = 21
Answer:
B) 20 and E) 40
Step-by-step explanation:
4 = 2*2= 2²
10=2*5
Common denominators = 2²*5=4*5=20
20,40
They are the opposite signs of the ones there, so x = 2 and x = -7

N = 22b+34
Plug in.
n = 22(2)+34=44+34=78
n = 22(3)+34=66+34=100
n = 22(5)+34=110+34=144
n = 22(7)+34=154+34=189
