Find the angle measures given the figure is a rhombus.

Mathematics

Answer:

1 = 90°, 2 = 66°

Step-by-step explanation:

Since the diagonals of a rhombus are perpendicular, ∠1 = 90°. Using the Exterior Angles Theorem (exterior angle = sum of remote interior angles, we see that ∠2 = 90 - 24 = 66°.

What are quartiles and how do you find them?

Neporo4naja [7]

Answer:

Quartiles are the values that divide a list of numbers into quarters

Step-by-step explanation:

Step 1: Put the numbers in order: 2, 5, 6, 7, 10, 12 13, 14, 16, 22, 45, 65. Step 2: Count how many numbers there are in your set and then divide by 4 to cut the list of numbers into quarters. There are 12 numbers in this set, so you would have 3 numbers in each quartile. Interquartile Range: 8.5.

Hope this helps :)

several friends each had 2/5 of a bag of peanuts left over from the baseball game.they realized that they could have bought two

aleksandrvk [35]

Answer:

5 friends.

Step-by-step explanation:

Let x be the number of friends,

Since, each had 2/5 of a bag of peanuts left over,

Thus, the total numbers of bag left = 2/5 of the number of friends,

$=\frac{2}{5}x$

According to the question,

$\frac{2}{5}x=2$

$\implies x = 5$

Hence, there were 5 friends.

MATH HELP PLEASE! I NEED HELP IM DUMB

deff fn [24]

First of all...YOU'RE NOT DUMB!!! You just need some help! Being confident in your knowledge/skills is half the work! ;D

And second...

PART 1:

28. Polygon ABCDE is a pentagon (it has five sides). The sum of the interior angle measures for a pentagon is 540°. Here's what we know:

m<A = 90°

m<B = 90°

m<D = 90°

m<C = m<E

First, find the sum of the measures of angles A, B, and D.

(90)(3) = 270°.

Next, find the combined angle measure of angles C and E.

540 - 270 = 270°.

Finally, find the measure of angle E (or m<AED).

270 / 2 = 135°.

So, to fill in the blanks:

90 · 3 + x · 2 = 540

m<AED = 135°.

29.

(a) 360°

(b) hexagon

(d) hendecagon (11 sides)

I have attached a table containing a list of polygons, their side-count, and the sum of their interior angles.

PART 2:

Complimentary angles are angles whose measures add to equal 90°.

Supplementary angles are angles whose measures add to equal 180°.

30. 35° + 55° = 90°; Complimentary.

31. 62° + 108° = 170°; Neither.

Hope this helps!
