Angles a and b are supplementary angles. What is the value of m<a if m<b=43 dagees

Question

1. 223
2. 43
3. 137
4. 47

Answer 1

Since angles a and b are supplementary, their sum must equal 180 degrees.

Let m<a = x, then m<b = 43.

So, x + 43 = 180.

Subtracting 43 from both sides gives:

x = 180 - 43.

Simplifying gives:

x = 137.

Therefore, the value of m<a is 137 degrees.

The correct answer is option 3. 137.
