Answer:
180°
Step-by-step explanation:
a convex polygon has n sides, then its interior angle sum is
S = ( n −2) × 180°
S=(3-2)*180°=180°
(x-1)^2-4
If u put the vertex into vertex form you get this answer.
Answer:
0.75 and 10.00
Step-by-step explanation:
The value of x
3x°+46°+(2x-1°)=180°(angle sum of △)
5x+45=180°
5x=180°-45
x=135÷5
x=27
x is 27
put x into angle B,we have
2(27)-1
=53
thus angleB is 53°
