Answer:
third option
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (4, - 1) and r = 10÷ 2 = 5, thus
(x - 4)² + (y - (- 1))² = 5², that is
(x - 4)² + (y + 1)² = 25 ← equation of circle
AB = AC, so this is an isosceles triangle, then angle B=angle C =66⁰.
m∠BAD = m∠CAD, so AD is a bisector.
In an isosceles triangle, bisector is also median and height.
So AD is perpendicular bisector.
So angle x = 90⁰.
In triangle ABC
m∠A+m∠B+m∠C=180⁰
m∠A+66+66=180
m∠A=180-66-66=48⁰
m∠A=48⁰
AD is a bisector of A, so y=m∠A/2=48⁰/2=24⁰
x=90⁰, y=24⁰
Answer is A
Answer:
176 ÷ 22 = 8 132 ÷ 22 = 6
Last week, Kimberly read for 8 hours, and this week she read for 6 hours. So in total she read for 14 hours.
♥ Lets do this: X is 20% of 145
♥ Now our equation will look like this <span>x = 20% * 145
♥ </span>Converting percent to decimal:
♥ X = 20%/100 = 0.2
<span>♥ X = 0.2 * 14
♥ </span><span>X = 29
♥ Therefore 29 is 20% or 145
♥Hope this helps♥</span>
