Answer:
108°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2a is an exterior angle, thus
2a = a + 10 + 44 = a + 54 ( subtract a from both sides )
a = 54
Thus 2a = 2 × 54 = 108° ← exterior angle
J - Jose`s savings;
162 = 9 · j
j = 162 : 9
j = 18
Answer:
Equation is 9 · j = 162 and his savings is 18.
Total number of songs is ![14+16+17= 47](https://tex.z-dn.net/?f=%2014%2B16%2B17%3D%2047%20)
And out of 47, total number's of katy Pery's songs are 17.
So probability that the next song will be the song of Katy Pery is
![= \frac{17}{47}](https://tex.z-dn.net/?f=%20%3D%20%5Cfrac%7B17%7D%7B47%7D%20)
And therefore probability that the next song is not of Kety's pary's song is
![1-\frac{17}{47} = \frac{30}{47}](https://tex.z-dn.net/?f=%201-%5Cfrac%7B17%7D%7B47%7D%20%3D%20%5Cfrac%7B30%7D%7B47%7D%20)
And that's the required answer .
Answer:
scale factor (k) is 2
Step-by-step explanation:
Look at W and W'. W is (-2, -1), but W' says (-4, -2). 2 x 2 is 4 and 1 x 2 is 2. Both coordinates were multiplied by 2. The same goes for all the other vertices, so it would be k = 2.
