15x - 6 = -9
9(x+2) = 9x+2=11x
9+11x=19x
Right???
Answer:
36°
Step-by-step explanation:
The image of the question is obtained online and attached to the solution of this question.
The tent pole is the line in the middle of the triangle and it is stated explicitly in the question that this tent pole bisects the angle that the two sides make with each other at the top.
So, the angle that the tent pole makes with each side = (72°/2) = 36°
Hope this Helps!!!
Answer:
Lower bound = 5.2
Upper bound = 5.4
Step-by-step explanation:
If a= 4.2 to (1dp):
Upper bound = 4.2 + 0.05 = 4.25
Lower bound = 4.2 - 0.05 = 4.15
If b = 18 (to the nearest whole number)
Upper bound = 18 + 0.5 = 18.5
Lower bound = 18 - 0.5 = 17.5
Therefore:
Lower bound of ((a+b)/a) = ((4.15 + 17.5) / 4.15) = 5.2 to 1 decimal place
Upper bound of ((a+b)/a) = ((4.25 + 18.5) / 4.25) = 5.4 to 1 decimal place
The upper and lower bound are calculated to one decimal place.
Answer:
I am sorry but if this is wrong but i think it is either 21,because it is divisible by 3 and 12 / 3 = 4 which is a denominator
Step-by-step explanation:
21 because it is divisible by 3 and 12 / 3 = 4 which is a denominator.
