Answer:
1. X = 14
2.X =13
Step-by-step explanation:
The angles are 90 degrees. I did math to check if the x values are correct and they are.
X=14
Y=15
Im assuming you want to find out what x and y are
Answer:
x=15
Step-by-step explanation:
21:2x=7:10 can be rewritten as 21/2x=7/10
21/2x=7/10, cross multiply
= 14x=210
x=15
Answer:
In the case of the equilateral triangle, , the exterior angle, plus 60 equals 180. Subtracting 60 from both sides of this equation gives us a value of equal to 120. This means that the exterior angle of an equilateral triangle is equal to 120 degrees. The sum of all the exterior angles is always 360 degrees.
