Answer: $0.32
Step-by-step explanation:
128 / 8 = 16
1 / 16 = 0.0625
0.0625 * 5.12 = 0.32
Simpler Answer:
128 / 8 = 16
5.12 / 16 = 0.32
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 °

Step-by-step explanation:
calculator
Answer:
a) Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
b) The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as
98 square feet
Step-by-step explanation:
The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.
The correct area =
15(2x + 7).
= 30x + 105 square feet
The error in Shawn’s expression is
= 15(2x + 7)
= 30x + 7 square feet
Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as
30x + 105 square feet - 30x + 7 square feet
= 30x + 105 - (30x + 7)
= 30x - 30x + 105 - 7
= 98 square feet
