Using the formula sum of interior angles {180(n-2)}
180(15-2)=180
giving you a total of 2340 Degrees
answer a)
soln,
or, 4x + 84 = 180° [being co-interrior angle]
or, 4x = 180 - 84
or, 4x = 96
or, x = 96/4
x = 24
answer b)
soln,
or, 2x + 5 = 135° [being corresponding angle]
or, 2x = 135 - 5
or,2x = 130
or, x = 130/2
x = 65°

well if it's helpful mark me as brainlest please
I believe the answer is 116.
23-8=15
8*15=120
sqrt2=4
the number 120-4=116
that’s what i got not sure if that is correct
Answer:
79.986
Step-by-step explanation:
Let A represent isotope ⁷⁹Br
Let B represent isotope ⁸¹Br
From the question given above, the following data were obtained:
For Isotope A (⁷⁹Br):
Mass of A = 79
Abundance of A (A%) = 50.69%
For isotope B (⁸¹Br):
Mass of B = 81
Abundance of B (B%) = 49.31%
Relative atomic mass of Br =?
The relative atomic mass (RAM) of Br can be obtained as follow:
RAM = [(Mass of A × A%) /100] + [(Mass of B × B%) /100]
= [(79 × 50.69) /100] + [(81 × 49.31) /100]
= 40.0451 + 39.9411
= 79.986 amu
Thus, the relative atomic mass of Br is 79.986
26 buckets. First I did 25.5 - 5.2 and got 20.3. Then I did 20.3 times 1000. Then divided that answer by 800. And got 25.375. Which rounds to 26.
