You use the formula C=2(3.14)r r is the radius and in this situation 2 so the answer will be 12.56
A. 15+18 is the correct answer by using distribution property
<u>Answer-</u>
<em>The value of x is </em><em>10</em>
<u>Solution-</u>
When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.
When the line are parallel the corresponding angles are equal in measurement.
As m and n are parallel line, so




A triangle interior angles add up to 180
so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees
