Answer:
x = 4
Step-by-step explanation:
<u>All triangles add up to 180 degrees</u>
76 + 17x + 9x = 180
76 + 17x + 9x - 76 = 180 - 76
26x / 26 = 104 / 26
x = 4
Answer: x = 4
I got 200 from a octagon with the diameter of 10
Answer:
(-8/7 ; 5/7)
Step-by-step explanation:
5t + 1/2s = 3 - - - (1)
3t - 6s = 9 - - - - - (2)
Multiply (1) by 12 and (2) by 1
Add the result to eliminate s
60t + 6s = 36
3t - 6s = 9
____________
63t = 45
t = 45 / 63
t = 5/7
Put t = 5/7 in either (1) or (2) to obtain the value of s
3(5/7) - 6s = 9
15/7 - 6s = 9
-6s = 9 - 15/7
-6s = (63 - 15)/7
-6s = 48/7
s = 48/7 * - 1/6
s = - 8/7
Answer:
x < -3
Step-by-step explanation:
subtract 4x: 4x + 9 < -3
subtract 9: 4x < -12
divide by 4: x < -3
