Answer:
x=37°
y=6
Step-by-step explanation:
(ASSUMING BD is a perpendicular bisector of AC, otherwise answers maybe be wrong)
Consider the triangle ABC:
AB is the same length as BC (marked), meaning ABC is an isosceles triangle.
Since ABC is isosceles, ∠BAC=∠BCA=53
All angles in a triangle add up to 180:
180=∠ABC + ∠BAC + ∠BCA
180= ∠ABC + 53 +53
∠ABC = 180 - 106
∠ABC = 74
Assuming BD bisects ∠ABC perfectly, x is half of ∠ABC.
x=74/2=37
If BD bisects AC perfectly, AD=DC=y=6
Answer:
x = ± 
It didn't insert but just look up the quadratic formula.
x = ± root [(b²-4ac]/2a]
I counted 72 letters and 17 words so...
72/17 = 4.23 to the nearest whole number: 4 letters per word
The decimal equivalent of 3/5 is 0.6 .
(0.6) x (65 mi/hr) = <em>39 mi/hr </em>
Answer:
44°
Step-by-step explanation:
The sum of the angles in a triangle = 180°
In an isosceles triangle the base angles are equal, thus
base angle = 
= 
= 44°
