Step-by-step explanation:
Question 8)
2,8,14
d=a2-a1
d=8-2=6
a77= 2+ (76)*6
a77= 2+456=458
a77= 458
Question 9)
-12,-17,-22
d= -17+12= -5
a82= -12+ (81)*(-5)= -12-405= 417
a82= 417
Question 10)
9,13,17
d= 13-9= 4
a49= 9+ (48)*4= 201
a49= 201
Hm..I'm pretty sure the answer is 34
Answer:
x = 12
Step-by-step explanation:
given 2x - 7 = 5 + x ( subtract x from both sides of the equation )
x - 7 = 5 ( add 7 to both sides )
x = 12
Answer=65° & 130°
195°=angle1+angle2
195°=(11+4x)+2(11+4x)
195°=33+12x
subtract 33 for both sides
162=12x
13.5=x
Now lets solve for the measure of the angles
angle1=11+4x
angle1=11+4(13.5)
angle1=11+54
angle1=65°
angle2=2(11+4x)
angle2=2(11+4(33.5))
angle2=2(11+54)
angle2=2(65)
angle2=130°
