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:
x = 11
Step-by-step explanation:
distribute: 4x - 28 = 27 - x
add x to both sides: 5x - 28 = 27
add 28 to both sides: 5x = 55
divide 5 to both sides: x = 11
Step-by-step explanation:
here is the right answers
Answer:
A. 320 sq. ft.
B. $1920
Step-by-step explanation:
You need to find 5 sides. They are all 8*8. 64*5 is 320. Now, you multiply that by 6 to get $1920
Answer: The answer is f(x) = 0.8(2x).
i just did the quiz and got it right
hope this helps you :)
