Answer:
k = 10
Step-by-step explanation:
the sum of any two interior angles is equal to the exterior angle of the unknown interior angle
4k+5 + 6k+10 = 115
10k + 15 = 115
10k = 100
k = 10
Answer:
Change the value of years to months.
Step-by-step explanation:
Western Beach: f(x) = -2x + 100
Dunes Beach: g(x) = 5x + 20
1 Year = 12 Months
Months will make the width interception more accurate.
There, I hope this helps... If you have any questions please feel free to ask me!!
21.4*pi(r^3)/3=1000 ,so use r from it to calculate SA=4*pi*(r^2)
don't ask me to do it completely unless u are unable to do it.
22.yes, 1:6
Use the sine rule.
For any triangle: sin(a) / A = sin(b) / B = sin(c) /C
Where A is the side opposed to angle a, B is the side opposed to angle b, and C is the side opposed to angle c.
Here, sin(B) / AC = sin(A) / BC = sin (C) / AB
<span> BC = 12.35, AC = 8.75 centimeters, and m∠B = 37°
sin(37) / 8.75 = sin(A) / 12.35 => sin (A) = 12.35 * sin(37) / 8.75
sin(A) = 0.845 = A = arctan(0.845) = 58.15°
And A + B + C = 180° => C = 180 - A - B = 180 - 58.15 - 37 = 84.85
Answer:
measure of angle A = 58.15°
measure of angle C = 84.85 °
