Answer:
162
Step-by-step explanation:
Sum of the interior angles of any triangle equal to 180 degrees thus :
60 + 70 + 8x + 2 = 180
8x + 132 = 180
Subtract both sides 132
8x + 132 - 132 = 180 - 132
8x = 48
Divide both sides by 8
8x ÷ 8 = 48 ÷ 8
<h2>x = 6 </h2>
Answer:
Spiders=8
Ants=12
Step-by-step explanation:
Spider(s)=8 legs
Ants(a)=6 legs
Total legs=136
Total heads=20
8s+6a=136 (1)
s+a=20 (2)
From (2)
s=20-a
Substitute 20-a into (1)
8s+6a=136
8(20-a)+6a=136
160-8a+6a=136
160-2a=136
-2a=136-160
-2a=-24
a= -24/-2
a=12
Substitute a=12 into (2)
s+a=20
s+12=20
s=20-12
s=8
Answer:
40 degrees
100-60=40
Step-by-step explanation:
The angle x is in another angle that looks like 100 and 100 minus 60 is 40.
Hope this helps and if it is correct.
