Answer:
Option 1: 2x + 11 = 90.
x = 79/2 or 39.5 degrees
Step-by-step explanation:
Option 1: You know that the angle for option one is 90 degrees because of the marking. Since you know that part of the angle is 11 degrees, you can set up an equation for 2x + 11 which equals to 90 degrees.
also jackie has 8 apples and mark has 4 apples
option B is correct
a+4=b =>
a+b=12
(a+4) + a =12
1/49
7^2 = 49
7^-2 = reciprocal of 49 = 1/49
it's the only one that hasn't been with a positive 2
