Answer:
99°
Step-by-step explanation:
- m∠VUT = 10x + 9
- m∠BUT = 7x - 1
- m∠VUB = 37°
- m∠VUT = ?
<u>We see that</u>
- m∠VUT = m∠BUT + m∠VUT
- 10x + 9 = 7x - 1 + 37
- 10x - 7x = 36 - 9
- 3x = 27
- x = 9
<u>Angle VUT measures:</u>
Answer:
1) Distance=Speed*time
90=(x+1)*(x)+(2x+5)(x-1)
90=x^2+x+2x^2-2x+5x-5
3x^2+4x-95=0
2) 3x^2+4x-95=0. Using quadratic formula, we get
x=(-4±sqrt(16-4*3*(-95)<u>)</u>)/6, x=5 or - 19/5 but since x also represents time, it can't be negative.
3) Total time take she took for the journey is x+x-1=2x-1=2*5-1=9 hours
Answer:
3y+x
Step-by-step explanation:
commutative property :
a+b=b+a
Similarly:
x+3y=3y+x
A ray has only one endpoint and goes on forever in the other direction. A segment has two endpoints
