Answer:
The slope is 1.181818182 or just round to 1.18.
Step-by-step explanation:
The answer is C) m∠1 + m∠2 = 90
Explanation: So ∠1 is x and ∠2 is x-4
Basically you know than ∠3 is 90° ... And a straight line is 180° .. So technically we can just find out 180-90 is 90(the other angle 1 + 2).
To get 90° we'll add ∠1 and ∠2 in other ways, like technical thinking-
So you already know adding ∠1 and ∠2 is 90°. So ∠1 + ∠2 = 90°
In other words you can say m∠1 + m∠2 = 90
For this case we must find the value of the following expression:
When:
Substituting the given values we have:
Finally, the value of the expression is 394.
Answer:
The value of the expression is 394.
