Answer:
Step-by-step explanation:
I guess this exercise is about translating the problem directions to math language...
The first part states "nine more than...". Usually, "more than" can be translated to addition, in this case the addition of 9 and an expression that needs to be determinated. This can be translated to math language as:
9 + ... (1)
The second part of the statement says "the quotient of two and a number x". Quotient means division, in this case the division of 2 and x. Then we have:
... + (2)
Putting (1) and (2) together, the answer is
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 )
