They are the same angle, so we can write an equation to resemble it.

2w - 5 = 95

Solution:

2w - 5 = 95

2w = 100

w = 50

Check:

2(50) - 5

100 - 5

Therefore, w = 50

Best of Luck!

Answer:

x = 9

Step-by-step explanation:

We know sum of interior angles of a polygon = $(n-2)\times 180$

For a triangle (having n = 3),

Sum of interior angles = (3 - 2)×180°

= 180°

In ΔVWX,

m∠V = (12x + 19)°

m∠W = (2x + 19)°

m∠X = (x + 7)°

And m∠V + m∠W + m∠X = 180°

(12x + 19)° + (2x + 19)° + (x + 7)° = 180°

(12x + 2x + x) + (19 + 19 + 7) = 180°

15x + 45° = 180°

15x = 180° - 45°

x = $\frac{135}{15}$

x = 9

Therefore, value of x = 9.

The triangle below is isosceles. If ∠C≅∠B, then what is BC, in units?

ladessa [460]

Answer:

Step-by-step explanation:

If angles C and B have equal degrees then the side AC is also equal to side AB in length and you can make their equations equal as well and solve for X.

2x+16=7x+6

get X's all on same side and the constants all on the other side,

-2x +2x+16=7x+6+-2x

The X's on the left cancel out.

16=5x+6

-6+16=5x+6+-6

add -6 to each side. On the right the 6 is now cancelled out.

10=5X

divide each side by 5 to cancel out the 5

10/5= 5X/5

At the end of a year, the gross debt of a country stood at about $15 trillion. Express this amount in dollars per person, ass

Ilia_Sergeevich [38]

Answer:

The country's debt is $ 48,543.68 per person.

Step-by-step explanation:

Given that at the end of a year, the gross debt of a country stood at about $ 15 trillion, to determine this amount in dollars per person, assuming that the population of the country is about 309 million, the following calculation must be done:

15 trillion = 15,000,000,000,000

15,000,000,000,000 / 309,000,000 = X

15,000,000 / 309 = X

48,543.68 = X

Therefore, the country's debt is $ 48,543.68 per person.

Work out the size of angle X. X Х 33° 20° 165°

vitfil [10]

Answer:

142 degrees

Step-by-step explanation:

The sum of angle in a quadrilateral is 360 degrees

33 + 20 + 165 + X =360

53 + 165 + X = 360

218 + X = 360

X = 360 - 218

X = 142

Hence the size of angle X is 142 degrees
