Hey!!!

<a and <b are complementary angles.

Those angles which are exactly 90 degree are called complementary angles.

hope it helps..

Given ABCE is a rectangle, D is the midpoint of CE Prove AD =~ BD

Bas_tet [7]

Since the congruent operator is â‰… and since AD is congruent to BD, I'm going to assume that you want to prove that AD is congruent to BD.
1. DE is equal to CD by definition since D is the midpoint of CE.
2. AE is equal to BC since opposite sides of a rectangle are equal to each other.
3. Angle AEC is equal to Angle BCE since all angles in a rectangle are right angles and all right angles are equal to each other.
4. Triangles ADE and BDC are congruent to each other because we have SAS congruence for both triangles.
5. AD is congruent to BC since they're corresponding sides of congruent triangles.

Find the exact value of Cos 240 degrees without a calculator. Show your work!

VMariaS [17]

it equals (−12) because cos(60∘)=12

Explanation:

The reference angle for 240∘ is 60∘ (since 240∘=180∘+60∘)

60∘ is an angle of one of the standard triangles with
cos(60∘)=12

240∘ is in the 3rd quadrant so (either by CAST or noting that the "x-side" of the associate triangle is negative)
cos(240∘)=−cos(60∘)

cos(240∘)=−12

#1

-6-3-5

Hence inequality will be

$\\ \sf\longmapsto -6\leqslant 5$

#2.

3<5

But we need inequality

$\\ \sf\longmapsto 3\leqslant 5$

#3

The inequality given by

$\\ \sf\longmapsto -6\leqslant 3\leqslant 5$

An apple farmer is deciding how to use each day's harvest. She can use the harvest to produce apple cider or apple juice for the

Andreas93 [3]

Answer:For this item, we let x and y be the number of bushels of apple that will be used to produce apple cider and apple juice, respectively. The situation above is best represented by the following equations,

x + y = 18

20x + 15y = 330

The values of x and y from the equations above are 12 and 6, respectively. Therefore, 12 bushels will be used to make apple cider and 6 bushels will be used to make apple juice.
