Question

What is the Equation

Answer 1

Answer:

90+30+2x=180

Step-by-step explanation:

2x is an angle, so we need to find its measure

square symbol at corner of triangle means 90 degrees

we know the angle at the top corner is 30 degrees

the sum of all the angles in a triangle is 180 degrees

so the sum of 90 degrees, 30 degrees, and 2x degrees is 180 degrees

translate it to mathematical format: 90+30+2x=180
