Question

Need help on geometry TO PASS My Class so can you help please

Answer 1

Since it's a equilateral triangle.

`\\ \sf\longmapsto 5x+5x+5x=180`

`\\ \sf\longmapsto 15x=180`

`\\ \sf\longmapsto x=12`

• m<S=5x=60°

Answer 2

x=12

Explanation:

since it is an equilateral triangle the angle r all the same the angle have to equal 60
