the answer is 203/16 or 12.6875
In order to find the other end point we must know where the End point is.
·(5,-3)
In order to find out the new point we must know how long the line segment is.
·8 units.
Knowing this we would use the equation ΔY/ΔX to find the new point
·ΔY= Y²-Y
·ΔX=X²-X
Knowing this we just plug our points in, and we use process of elimination to get our answer.
First we will try choice A.
· (5,-3)
·(-3,-3)
To get from Y²⇒Y= 8 Units, and to get from X²⇒X=0 Units.
·8+0=8
-In conclusion your answer is A, i hope this is the answer you are looking for, feel free to post your questions here on brainly in the future.
Answer:
A =24.7° ; B = 40.6° ; C =114.7°
Step-by-step explanation:
Cosine Law
a² = b²+c²-2bc cos A
b² = c²+a² -2ca cos B
Sum of three angles of a triangle is 180°.
a = 34 ; b= 53; c = 74
Substituting the given values in the cosine law, we have
34² = 53² + 74² - 2*53 *74 * cos A
7844 cos A = 2809 + 5476 - 1156 = 7129
cos A = 7129/7844 = 0.9088
A = cos⁻¹ (0.9088) = 24.6600° = 24.7°
53² = 74² + 34² - 2 (74)(34) cos B
5032 cos B = 5476 + 1156 - 2809 = 3823
cos B = 3823/5032 = 0.7597
B = cos⁻¹ (0.7597) = 40.5622° = 40.6°
Also, A + B + C = 180°
24.7 + 40.6 + C =180
C =180 - 65.3 = 114.7°
∴ A =24.7° ; B = 40.6° ; C =114.7°
Point U is at (2, -3).
I hope this helps!
I believe the answer is A
