The length of CA is opposite of angle B and since the hypotenuse is known, you can write an equation like this: sin 40 = x/7 which simplifies to sin40 * 7 = x. The answer is A
I think the principal is 2,377.18. Principal is what you wanted correct?
Answer:
Q11. 20x=120° (vert opp angles)
x=120÷20
=10
Q12. x+68°=60° (vert opp angles)
x=60-68
=-8
Q13. 80°+x+106°=180° (int angles, u//v)
x+186°=180°
x=180-186
=-6
Q14. 6x+8°=50°
6x=50°-8°
=42°
x=42÷6
=7
Answer:
113.1 cm³
Step-by-step explanation:
The volume of a sphere of radius r is V = (4/3)πr³.
If the radius is 3 cm and the answer is to be expressed to the nearest tenth, then we get:
V = (4/3)(3.14159)(3 cm)³
= (4/3)(84.82 cm³
= 113.1 cm³
The answer is y = 3x + 5
explanation : if you substitute the x in the equation for 0 and the y for 5 then solve/simplify. if you’re still not sure you can try the next one and substitute x for 2 and y for 11. you’ll see that y and x will equal each other. hope this helps:)
