Answer:
(- 1/2 , √3/2)
Step-by-step explanation:
t=20π/3
t' = 20π/3 - 6π = 2π/3 (120°) ... 2nd quadrant
If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)
OF/OE = - cos 60° = x / 1 = - 1/2
FE/OE = sin 60° = y/1 = √3/2
Answer: The answer is all real numbers greater than or equal to 2
Step-by-step explanation:
Answer:
6. yes they are congruent, they are exactly the same shape and size
7. no they are not congruent, they are different sizes
8. they are congruent, they have the same shape and size
Step-by-step explanation:
Answer:
She messed up the equation, A= B x h, she changed it midway, and also, you need to add the one half to make the equation valid
Step-by-step explanation:
A=1/2 x b xh
17.5 = 1/2 x 5 x h
35=5h (multiply both sides by 2 to get rid of one half)
35/5 = 5h/5
7=h
The height of the triangle is 7 units
