Question

solve for x if the angles are 110 and 2x+3

Answer 1

Answer:

x=16

Step-by-step explanation:

Because this is an isosceles triangle the angle 2x+3 is the same as the missing angle. The angles in triangles add up to 180 degrees. 180-110=70.

Because the two angles are the same you can divide 70 by 2 to get 35.

35=2x+3.

35-3=2x+3-3

32=2x

32/2=2x/2

16=x

Answer 2

Since the triangle is an isosceles triangle, it’s base angles are equal which means two angles are 2x+3 and other angle is 110
Then
2x+3+2x+3+110=180(sum of angles of triangle)
4x+6=180-110
4x+6=70
4x=70-6
4x=64
x=64/4
x=16
