Answer:
x=40
Step-by-step explanation:
<h3> firstly
180 -110 = 70 (sumnof angle of a straight line ) </h3><h3>
180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle </h3><h3>
180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle there fore 70 +70 +x= 180 </h3><h3>
180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle there fore 70 +70 +x= 180 140+x=180 sum of angles of a triangle </h3><h3>
180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle there fore 70 +70 +x= 180 140+x=180 sum of angles of a triangle x=180 -140 = 40 </h3>
Answer:
