Answer:
x=21
<EAF=52°
<EAL=104°
Step-by-step explanation:
Since it has a bisector, the two angles are equal.
2x+10=3x-11
10+11=3x-21
21=x
<EAF=2x+10 = 2(21)+10 = 42+10 = 52°
<EAL=52*2=104°
so x=5
substituting for x in the equation we get:
Ans C: 16
a) 4(t - r) = 4(6 - 2.5) = 4 x 3.5 = 14
b) 4t - r = (4 x 6) - 2.5 = 24 - 2.5 = 21.5
c) 2(3t - 10) = 2(3 x 6 - 10) = 2(18 - 10) = 2 x 8 = 16
d) (t - 2)² = (6 - 2)² = 4² = 4 x 4 = 16
e) cannot decipher the equation
f) 6r + t = 6 x 2.5 + 6 = 15 + 6 = 21
