Answer:
Step-by-step explanation:
Given the algebraic expression;
To make n the subject of formula.
Cross-multiplying, we have;
Rearranging the equation, we have;
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
Answer: the answer is 12
Step-by-step explanation:
8
You can divide it to 6 square and a triangle
The triangle is 2
2 + 6 = 8
