Answer:
67.0 square units
Step-by-step explanation:
The formula for the area is ...
Area = 1/2ab·sin(C)
Area = (1/2)(14)(28)sin(20°) ≈ 67.036 . . . . square units
The area of the triangle is about 67.0 square units.
Answer:
Step-by-step explanation:
Part A.
Expression
= 10
Because 100 =
and ![[(10)^2]^{\frac{1}{2}}=10^1=10](https://tex.z-dn.net/?f=%5B%2810%29%5E2%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D10%5E1%3D10)
[Since,

Part B.
When simplified, the answer is RATIONAL.
[Since, 10 can be written as

No, it is not a valid inference because her classmates do not make up a random sample of the students in the school.
Answer:
incorrect
Step-by-step explanation:
To determine if the triangle is right
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right, that is
longest side = 10 and 10² = 100
6² + 8² = 36 + 64 = 100
Thus the triangle is right.
She should have added 6² and 8² and compared that to 10²
