Answer:
<h2>- 234</h2><h2 />
Step-by-step explanation:
a83 = 12 + (83 - 1)(-3) = 12 + (82)(-3) = -234
Answer:
4
Step-by-step explanation:
÷ 
(20-4) ÷ 4
16 ÷ 4=4
In advance, I hope nothing I say sounds condescending; I just don’t know how much you know lol. Also geometry sucks
They’re vertical angles (they’re opposite angles when 2 lines intersect). Since vertical angles are congruent, we can set up an equation to solve for the value of x.
If they’re both equal, we’ll say exactly that in our equation!
2x + 90 = 4x + 30
Combine like terms
2x = 60
Simplify
x = 30
Now, just plug in 30 for one of the x values in either of the equations
2(30) + 90 = 150
Angle = 150 °
Hope this helped!
11 if you multiply 11 by both the number and and the variable you’ll get 11x-55=66. Add 55 to each side which will give you 121 then divide that by 11
