Answer:

Through pythogoras theorem

a^2+b^2=c^2

20^2+16^2=c^2

c^2=400+256

c^2= 656

c= square root of 656

c=25.6 inches or 30 inches

Missing side 25.6 inches or 30 inches

c^2 = a^2 + b^2

c^2 = 16^2 + 20^2

c^2 = 256 + 400

c^2 = 656

Now, square root both sides to find the missing length of c or the hypontenuse.

Answer: c = 25.6 inches

(5) Find the value of the variable. The diagram is not to scale.

Answers

Answer:

x = 19 degrees

Step-by-step explanation:

180 - 114 = 66

d. The opposite of - 10t and t - 10t

Answers

Answer:

The sum is [tex]t[/tex].

Step-by-step explanation:

Consider the provided information.

The given expression are - 10t and t - 10t

We need to find the sum of the opposite of -10 t and t - 10t.

The opposite of -10 t is 10 t.

[tex]10t+(t-10t)[/tex]

Remove the parenthesis.

[tex]10t+t-10t[/tex]

Simplify the number

[tex]10t-10t+t[/tex]

Use Additive inverse.

[tex]t[/tex]

Hence, the sum is [tex]t[/tex].

Complete the square x² + 16.0

Answers

Answer:

x^2 + 16x + 32

Step-by-step explanation:

I am going to guess this is from factoring.

In which you need to x's multiplied together to get x^2. So you have:

(x+?) (x+?)

to get 16x you need two 8x's in your factoring square. so it would be

(x+8) (x+8)

Now you found out what you were mulitpling together, then you solve. The final part is multiplying 8 by 8, which is 32.

select the correct solution for 6x = 30
(A) x = 24
(B) x = 1/5
(C) x = 5
(D) x = 36

Answers

Answer:

answer is (C) x = 5

I hope it helps you

:-))

There are two ways to solve this u can divide the 30 by 6 (30/6=5) or you can ask yourself what numbers times 6 is equal to 30? 6 time ? =30 which is also equal to 5.
So that would make (c) x=5 the correct answer

Square ABCD has diagonals AC¯¯¯¯¯

and BD¯¯¯¯¯

. What is m∠ABD

A

180º

B

90º

C

45º

D

360º

Answers

Answer:

option (c)

Step-by-step explanation:

Given,

ABCD is a square.

AC and BD are diagonals

We know that,

Sides of the square make 90 degrees with each other.

And Diagonals bisect the opposite angles of the square.

Now,

[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]

[tex]\angle ABC = 90^\circ[/tex]

[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]

[tex]\angle ABD = \dfrac{90^\circ}{2}[/tex]

[tex]\angle ABD = 45^\circ[/tex]

Hence, option (c) is correct.

The area is 3.14 for number 6

Answer:

Step-by-step explanation:

the top one... which is I am assuming asking for the diameter?

Formula = d=2r  

so 2x4 which is 8

But if you were wanting number 6

the formula is A=πr2

which would be 3.14 x 1^1 = 3.14

you take the diameter and square it and then multiply it by pi
