Answer:
x = 12 degree
Step-by-step explanation:
3x + 19 + 5x = 115 degree (sum of two interior opposite angles are equal to the third side)
8x + 19 = 115
8x = 115 - 19
x = 96 /8
x = 12
Step-by-step explanation:
the value of root three is given already so the question is asking you to round it of to the nearest 1000 which means there should be three numbers after the decimal point.
The answer is 3. 20/2=10 10-7=3
Answer:
one
Step-by-step explanation:
for general form : ax²+bx+c=0
delta = b²-4ac
so for this example delta is 8²-4×2×8 =0
we know if delta = 0 , we have just one real number solution
so the answer is 1
