Two angles in a triangle add up to 85 degrees what is the size of the third angle

Answers

Answer 1

Answer: all of the angles in a triangle should add up to 180 degrees so if you know 2 out of three you just do subtract 180 by the sum of the two angles.
180-85=95

The width of kevin's yard is three times the width of his garage, increased by 12 feet. What expression describes the width of kevin's yard if g represents the width of his garage?

Answers

Answer:

The expression that describes the width of Kevin’s yard is (3g + 12) feet

Step-by-step explanation:

This is an expression problem.

From the question, we are made to know that the width of the yard is 3 times the width of the garage increased by 12 feet.

Now, we are told that the width of the garage is g feet and we want to find the width of the yard.

The width of the yard will be g feet * 3 + 12

Mathematically that would be 3g + 12 feet

{3} is a subset of {1, 2, 4, 5, 6} ?

Answers

No, a set is only a subset of another set if it only contains elements contained in the original set.
3 isn't an element of {1,2,4,5,6}, so {3} isn't a subset of {1,2,4,5,6}.

Evaluate......6!2!=?

Answers

Answer: The required value of the given expression is 1440.

Step-by-step explanation: We are given to evaluate the following expression involving factorials:

$E=6!2!.$

We know that

for any non-negative integer n, the factorial of n is defined as:

$n!=n*(n-1)*(n-2)*~.~.~.~*2*1.$

Therefore, the value of the given expression E will be

$E\n\n=6!2!\n\n=6*5*4*3*2*1*2*1\n\n=1440.$

Thus, the required value of the given expression is 1440.

Note that the required value of the given expression 6! 2! is 1440.

How is this so?

We are given to evaluate the following expression involving factorials -

E = 6! 2!

n! = x x (n-1) x (n-2 ) x .... x 2 x 1

Hence, , the value of the given expression E will be

= 6! 2!

= 6 x 5 x 4 x 3 x 2 x 1 x 2 x 1

= 1440

Recall that factorials are mathematical operations denoted by an exclamation mark (!) that represent the product of a positive integer and all positive integers less than it.
