Answer:
31.7 cm²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = 
absinC
where a, b are the 2 sides given and C the angle between them
∠ C = 180° - (72 + 59)° = 180° - 131° = 49° , thus
A = 0.5 × 12 × 7 × sin49° ≈ 31.7 cm² ( to 1 dec. place )
Answer:
8.067>8.06>8.006
Step-by-step explanation:
Remember that what ever the number is after the decimal is the the greatest.
The x coordinate of S will be 1/2 * 2a = a.
and since the half triangle is 30-60-90 the y coordinate will be sqrt3 a
so S is (a , sqrt3a)
The apothem of this is 13
Answer:
6 sets
Step-by-step explanation:
(“of”=multiply)
Step 1.
1/5 of 45 sets = 45 x 1/5 = 9 sets.
Step2.
2/3 of 9 sets = 9 x 2/3 = 6 sets
Final Answer:
6 sets
