TV−→− bisects ∠RTS. If the m∠RTV=(16x−6)° and m∠VTS=(13x+9)° , what is the value of x and the m∠RTV ?
natta225 [31]

Answer:

x = 5

RTV = 74

Step-by-step explanation:

Given

RTV=16x - 6

VTS=13x+9

Required

Determine the values of x and RTV

Since, TV is a bisector, then

RTS = RTV + VTS --- (1)

and

RTV = VTS -- (2)

Substitute values of RTV and VTS in (2)

16x - 6 = 13x + 9

Collect Like Terms

16x - 13x = 9 + 6

3x = 15

Solve for x

x = 5

Substitute 5 for x in RTV=16x - 6

RTV = 16 * 5 - 6

RTV = 80 - 6

RTV = 74

Katalin drove 300 miles on her vacation. She drove an average of 1.9 times faster on the second 150 miles of her trip than she d
Kay [80]
300=x+1.9x
I got this by dividing the problem into two parts x[the speed of the first half] plus 1.9x [the speed of the second half increased by 1.9] both of those together should give you 300. 
I went further and solved this...If you placed 103.5 into this problem for x you should get 300.15!

[Help asap, will mark brainliest when it allows me] Find the angle measures for the following triangle.
shutvik [7]

Answer:

x=53

x+2= 53+2= 55

Step-by-step explanation:

(x+2) + x + 72 = 180 (angles of triangle supplementary)

2x+ 74 = 180

2x = 180- 74

2x= 106

x= 106/2

x= 53
