Yeah sometimes I forget these things too.

Just add what’s in the bracket then square it.

(6+1)^2
7^2
= 49

CORRECT ONE GETS BRAINLIEST!!!!!!

Elza [17]

Answer:

CD = 11 units

Step-by-step explanation:

See the drawing attached

<h3>Given</h3>

C is midpoint of AB
B is between A and D
AD = 15
BD = 7
Find CD

<h3>Solution</h3>

CD = CB + BD =
1/2AB + BD =
1/2(AD - BD) + BD =
1/2(15 - 7) + 7 =
1/2(8) + 7 =
4 + 7 =
11

Find the distance between these points. A(5,8), B(-3,4)

konstantin123 [22]

Answer:

Distance between the points is 8.94 units

Step-by-step explanation:

General formula:

${ \boxed{ \bf{distance = \sqrt{ {(x_{1} - x _{2} )}^{2} + {(y _{1} - y _{2} ) }^{2} } }}}$

substitute:

${ \sf{ = \sqrt{ {(5 - ( - 3))}^{2} + {(8 - 4)}^{2} } }} \\ = { \sf{ \sqrt{64 + 16} }} \\ = { \sf{ \sqrt{80} }} \\ = 8.94 \: units$

How do I solve for y?

vivado [14]

Short Answer: y = 36°
Remark
What an interesting question!! The first thing you have to do is find out what the interior angle of a regular pentagon is. After you have done that, you can calculate y.

Method.
The exterior angles of a regular figure add up to 360°.

Step One
Find out the size of the exterior angles of a regular pentagon.
There are 5 such angles. They add up to 360°

5x = 360 Divide by 5
x = 360 / 5
x = 72°

Step Two
Find out the value of the interior angles of a pentagon.

Method
The interior and exterior angles add up to 180°
Exterior Angle + Interior Angle = 180°
Exterior angle = 72 degrees
72° + Interior Angle = 180° Subtract 72 from both sides.
Interior Angle = 180° - 72°
Interior Angle = 108°

Step Three
Solve for y.

There are 3 tiles each with an angle of 108° that are placed together. So y + 3 interior angles = 360°

y + 3*interior angles = 360°
y + 3*108 = 360
y + 324 = 360 Subtract 324 from both sides.
y = 360 - 324
y = 36°
