Question

Whatt is the answer? ​

Answer 1

Answer:

4

Step-by-step explanation:

In a equilateral triangle, all angles are 60 degree, so 10x+20=60

10x=40

x=4

Answer 2

Answer:

x = 4

Step-by-step explanation:

An equilateral triangle means that all three sides are equal. All triangles have an inner angle measure of 180 degrees. Divide 180 by 3 to find out a singular angle's measure. You end up with : 10x + 20 = 60. In order to isolate the 10x, subtract 20 from both sides. This gives you 10x = 40. Thus, x = 4.
