Answer:
Step-by-step explanation:
It's B.
So the equation is x > -25. In word form, "The solution to this equation is greater than -25."
B begins at -25, and has a thick arrow pointing in the positive direction.
Answer:
Step-by-step explanation:
If the radius of the circle is 2mm, the circumference is 4π mm.
Arc length of the quarter circle = π mm.
Perimeter of the quarter circle = arc length + 2 radii = 4π + 4 mm = 16.56 mm
90+44+(3n-5)=180
134+(3n-5)=180, subtract 134 from both sides
3n-5=46
3n=51
n=17
To check: 90+44+(3x17-5)=180
Answer:
cos x = 0.5
Step-by-step explanation:
Using the trigonometric identity
cot x =
Given
sin x cot x = 0.5, then
sin x × = 0.5 ← cancel sin x on numerator/ denominator
cos x = 0.5
