True
∠2 and ∠5 are both vertical at the vertex of the 2 straight lines
Answer:
m∠E=57°
Step-by-step explanation:
∠FDE=∠FED=(4x+1)° (base angles of isos triangle)
2(4x+1)+(5x-4)=180 (angle sum of triangle)
8x+2+5x-4=180
13x-2=180
13x=180+2
=182
x=182÷13
=14
Hence, m∠E = (4x+1)°
= [4(14)+1]°
= (56+1)°
= 57°
Answer:
7x + 7
Step-by-step explanation:
2x + 5x = 7x
5 +2 = 7
