Step 2 is wrong and i don't know the other question
Answer:
The answers for this are as followed:
Area = 906.12058 (Rounded to the nearest tenth = 906.1)
Perimeter = 138.94608 (Rounded to the nearest tenth = 138.9)
Semiperimeter = 69.47304 (Rounded to the nearest tenth = 69.5)
Step-by-step explanation:
This is an Acute Scalene Triangle, with the side and angle measurements being:
Side A = 49
Side B = 40.17851 (Rounded = 40.2)
Side C = 49.76757 (Rounded = 49. 8)
------
Angle ∠A = 65° = 1.13446 rad
Angle ∠B = 48° = 0.83776 rad = 4/15π
Angle ∠C = 67° = 1.16937 rad
------
∠C = 180° - A - B = 1.16937 rad = 67°
b = a·sin(B)/sin(A) = 40.17851
c = a·sin(C)/sin(A) = 49.76757
In order to find the area, just use the equation:
ANSWER = c. 63°
EXP:
>ABC = 1/2(x + y)
Answer:
SA=120 m^2
Step-by-step explanation:
SA=(9x5)+(3x4)+(9x4)+(9x3)
SA=120
Answer:
$1400
Step-by-step explanation:
Salary of a Sandy working as a Chef= $ 35000
Percentage of a salary spent on expenses= 4%
Amount of money spent on expenses= 4 % of $35000
Amount of money spent on expenses= $1400
Hence he spent $1400 on expenses
Hence, the correct answer is $1400
