Step-by-step explanation:
in ascending order;
4/15 ,1/5 ,2/3
All angles in a triangle add up to 180
So 79+37=116
180-116=64
Y=64
Hope this helps
This is how I would solve it:
1st # = x 4(x+1)=3x+18
2nd # = x+1 4x+4=3x+18
4x=3x+14
x=14
To check: 15x4=60; 60-42=18. <u>1st # = 14; 2nd # = 15.</u>
Answer:
520 m
Step-by-step explanation:
Perimeter is the distance around a shape. To find the perimeter, you add up all the sides.
200 + 60 + 60 + 200 = 520 m
