Answer:
its #3
Step-by-step explanation:
hope this helps
An angle bisector is a line or ray that divides an angle into two congruent angles
so
in this problem
m∠RST=m∠RSV+m∠VST
m∠RSV=m∠VST
hence
m∠RST=2*m∠RSV --------> equation 1
we have
m∠RST=(6x-24)
m∠RSV=(2x+8)
Substitute in the equation 1
6x-24=2*(2x+8)
6x-24=4x+16
6x-4x=16+24
2x=40
x=40/2
x=20 degrees
therefore
the value of x is 20 degrees
Tell me if I’m wrong
6x-3y=1 i hope this helps
Add 4 to both sides
-104 + 4 = -2(1 + 7x)
Simplify -104 + 4 to -100
-100 = -2(1 + 7x)
Divide both sides by -2
-100/-2 = 1 + 7x
Two negatives make a positive
100/2 = 1 + 7x
Simplify 100/2 to 50
50 = 1 + 7x
Subtract 1 from both sides
50 - 1 = 7x
Simplify 50 - 1 to 49
49 = 7x
Divide both sides by 7
49/7 = x
Simplify 49/7 to 7
Switch sides
<u>Answer: x = 7</u>
Answer:
B = 42.7 degrees, C = 102.3 degrees and c = 18.7.
Step-by-step explanation:
We use the Sine Rule:
a / sin A = b / sin B
11 / sin 35 = 13 / sin B
11 sin B = 13 sin 35
sin B = 13 sin 35 / 11 = 0.677863
B = 42.7 degrees.
So C = 180 - 42.7 - 35
= 102.3 degrees.
c / sin 102.3 = 11 / sin 35
c = 11 sin 102.3 / sin 35
= 18.7.
