Answer:
x = 5
Step-by-step explanation:
Given that,
First side of a triangle = x+2
The second side of a triangle = 8
The third side of a triangle = x
We know that, perimeter is equal to the sum of all sides. So,
x+2+x+8 = 20
2x+10 = 20
2x = 10
x = 5
Hence, the value of x is equal to 5.
Answer:
3.5
Step-by-step explanation:
By the Law of Sines,
LJ/sin(23°) = 9/sin(89°)
LJ = (9sin(23°))/(sin(89°), which is about 3.5
Answer:
GIVE ME MY RAMEN
Step-by-step explanation:
3.
add like terms
30 + 7k = 100
100-30 = 70
70 divided by 7k = 10
k = 10
4. add the z's together
2z - 6 -2 = -10
+ 6 + 2
-10 will be -2 now since we dragged the -6 and -2 to the other side
2z = -2
z = -1
5. 3.2x - 1.7x = 1.5x
1.5x + 5.5 = 10
10 would be 4.5 since we dragged 5.5 to the other side so it would be 10 - 5.5
3.2x = 5.5
x = 1.71875
6.
3/4x - 1/4x = 2/4x
14 - 3 = 11
2/4x = 11
x = 22
