Answer:

See below

Step-by-step explanation:

<u>Statement | Reason </u>

1. m∠A + m∠B + m∠C = 180° | 1. Angles in a triangle sum to 180°

2. 28° + x - 4° + 2x = 180° | 2. Substitution

3. x=(180° - 24°)/3= 156°/3°= 52° | 3. Algebra

Step-by-step explanation:

$f(3) = {(3)}^{2} + 3(3) - 7 = 9 + 9 - 7 \\ = 18 - 7 = 11$

$g(3) = 5(3) - 3 = 15 - 3 = 12$

$f(3) + g(3) = 11 + 12 = 23$

Answer:

y=1/2x-5

Step-by-step explanation:

We have slope so we just need to find the y intercept.

slope intercept formula is

y=mx+b

(m) is slope

(b) is y int

y=1/2x+b

now apply our given x and y values (4 & -3)

-3=1/2(4)+b

simplify

-3=2+b

subtract 2 from each side

-5=b

put that into our equation

y=1/2x-5

How many degrees are each angle of a regular 7 sided shape?

Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

Here is a diagram of a seven sided regular polygon. You use this diagram to find out how many degrees total are in the interior of a the heptagon. There are 5 such triangles which means that since each triangle has 180o the total amount of the interior angles must be 5 * 180 = 900

Since there are 7 interior angles, the answer to how large each one of them is is found by

900/7 = 129.57 which is slightly off because it is a rounded error.

In general, the size of the angles in a regular polygon

180(n - 2 ) / n

Where n is the number of degrees in each interior angle. For example for an 8 sided figure you would get

180(8 - 2) / 8 = 180 * 6/8 = 133 degrees.
