Answer:

Step-by-step explanation:

isosceles trapezoid = congruent sides in pairs and the same for the angles

<h2><u><em>angle 1 = 32°</em></u></h2><h2><u><em>angles 2 & 3 = 148°</em></u></h2>

the sum of the interior angles is 360°

so angle 1 = 32°

angles 2 and 3

(360 - 32 - 32) :2 = 148°

check

32 + 32 + 148 + 148 = 360°

the answer is good

(4x + 2y + 6) + (7x + 3y - 4) + (x - 2y + 1)
Amiraneli [1.4K]

Answer:

12x+3y+3

Step-by-step explanation:

Let's simplify step-by-step.

4x+2y+6+7x+3y−4+x−2y+1

=4x+2y+6+7x+3y+−4+x+−2y+1

Combine Like Terms:

=4x+2y+6+7x+3y+−4+x+−2y+1

=(4x+7x+x)+(2y+3y+−2y)+(6+−4+1)

=12x+3y+3

the measure of an interior angel of a regular polygon is 150. find the number of sides in the polygon.
adoni [48]

Answer:

The polygon has 12 sides.

Step-by-step explanation:

Recall that the expression for finding the measure of one interior angle of a regular polygon is \frac{180(n-2)}{n}, where n is the number of sides the polygon has (and n\neq 0), which is what we want to find.

Because the measure of one interior angle of the given polygon is 150\textdegree, we can write the following equation to solve for n:

\frac{180(n-2)}{n}=150

Solving for n, we get:

\frac{180(n-2)}{n}=150

\frac{180n-360}{n}=150 (Distribute the 180 in the numerator)

180n-360=150n (Multiply both sides of the equation by n to eliminate the denominator and simplify)

30n-360=0 (Subtract 150n from both sides of the equation and simplify)

30n=360 (Add 360 to both sides of the equation to isolate n and simplify)

\bf n=12 (Divide both sides of the equation by 30 to get rid of n's coefficient and simplify)

Therefore, the polygon has \bf 12 sides. Hope this helps!
