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

Step-by-step explanation:
To get from 3 to 7 is 4 and 4 to 2 is a -2. 4 divided by 2 is -2. A positive divided by a negative is a negative.
Answer:
$31.94
Step-by-step explanation:
29.99 x 0.065 = 1.95
29.99 + 1.95= 31.94 :)
3/7 = 0.4285714286.
The hundredth place is 2 places to the right of the decimal. In this case, it is 2. So we look to the number to the right of 2 (which is 8). 8 ≥ 5, so the 2 gets rounded to a 3.
0.43
Answer:
You should mail about 4000 letters each day.
Step-by-step explanation:
25% of 80,000 is 20,000
