Triangles have, naturally, 3 angles. The sum of all 3 angles will always be 180 degrees, no matter the triangle. Angles A + B + C will always equal 180 degrees.

55 + 80 + x = 180
x = 180 - 80 - 55
x = 45°

How to solve 4y=x 3x- y=70 using substitution
creativ13 [48]
X = 4y
3x - y = 70

substitute the x in the second equation with the other half of the first equation.

3(4y) - y = 70
12y - y = 70
11y = 70
y = 6.36 repeating, or 6 4/11

now use this to solve first equation
x = 4 (6 4/11)
x = 25.45 repeating

Guests at a pizza party are seated at three tables. The small table has 5 seats and 2 pizzas. The medium table has 7 seats and 3
bagirrra123 [75]

Answer:

the 5 seated table with the 2 pizzas got more each.

Step-by-step explanation:

\frac{5}{2} = 2\frac{1}{y2} pieces each

\frac{7}{3} = 2\frac{1}{3} pieces each

\frac{12}{5} = 2\frac{2}{5} pieces each

Now change the fractions s that they all have a common denominator.

2\frac{1}{2} = 2\frac{15}{30}

2\frac{1}{3} = 2\frac{10}{30}

2\frac{2}{5} = 2\frac{15}{30}

Thus meaning that the 5 seated table with the 2 pizzas got more each.

Find the measure of each marked angle.
Tatiana [17]

Answer:

x degrees = 50 degrees.

x + 50 degrees = 50  + 50 = 100 degrees

(180 - 3x) degrees = (180 - 3*50) = 30 degrees.

Step-by-step explanation:

In a triangle, the sum of all inside angles must be 180 degrees.

In this question:

The inside angles are: x, x + 50 and 180 - 3x.

Then

x + x + 50 + 180 - 3x = 180

2x - 3x = -50

x = 50

So

x degrees = 50 degrees.

x + 50 degrees = 50  + 50 = 100 degrees

(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
