Answer:
?
Step-by-step explanation:
Answer:
First notice that θ is in quadrant I, where the sine and tangent will also be positive.
Then draw the angle in quadrant I. Drop a perpendicular to the x axis.
Since cosθ= 7/25, label the horizontal leg 7, and the hypotenuse 25; the vertical leg will be 24 by Pythagorean theorem.
Then sinθ=vertical/hypotenuse= 24/25 and tanθ= vertical/horizontal= 24/7
Step-by-step explanation:
Answer:
42
Step-by-step explanation:
We use (BODMAS) :
Brackets
Order/Index
Division
Multiplication
Addition
Subtraction
Now we do bracket first :
7(3²) = 7(9) = 63
Now we do division :
63÷3 = 21
Now we do multiplication :
2 × 21 = 42
Hope this helped and have a good day
Answer:
