You can tell when you cant draw an even L shaped figure at the intersects of the bottom and the side. 90 degrees. But there are many different ways that may make more sense. Happy to help:)
The first one is correct.
Answer:
We see that the big triangle is an equilateral triangle, so all its angles will measure 60°. Therefore x° will be 60° - 30° = 30°, as he's the base angle of an isosceles triangle having the other base angle of 30°. y will simply be 180° - 60° (remembering that the sum of the angles in a triangle is always 180°).
Answer:
2x+23
Step-by-step explanation:
The perimeter of a triangle is calculated by adding the sum of all sides.
Therefore, in the given problem, the perimeter will be:
Perimeter = 21-x + 2x-3 + x+5
= 2x+23
