90 percent of 70 is 63.
The answer is 70.
Answer:
so first we will find the interior angle:
1 angle : 31 (given )
2 angle :31 ( the base angles of isoscles triangle are equal)
3 angle : 31 + 31 + x = 180 ( angle sum property of triangle)
x = 180 - 62 = 118
now the exterior angles :
1 angle : 180 - 31 = 149 ( exterior angle and the angle adjacent usually forms a line (= 180) )
2 angle : 149 ( same reason as the first)
3 angle : 180 - 118 = 62 ( same reason as the first)
( i dont know if there is any other way, but this is one)
Answer:
CAN YOU HEAR THE SILIECE
Step-by-step explanation:
Answer:
x= 2
y = 20
Step-by-step explanation:
y = 6x + 8
y = –4x – 2
y = 4 (6x + 8
)
y = 6 (–4x – 2)
y = 24x + 32
y = –24 -12
___________
y = 20
input that back into the equation to find x
20 = 6x + 8
20 - 8 = 6x
12 = 6x
x= 2
You just have to use the squares one to factor this and this is what I got.
