What is the measure of the missing angle?

Triangle with two angles labeled
What is the measure of the missing angle? Triangle with - 1

Answers

Answer 1
Answer: Ive already solved this =/ the answer is 40 becuase the grand total sum of all the angles on a triangle is always 180 and because we already have 140 of that taken care of (70+70=140) we know that 180-140=40 therefore 40 is are missing angle.

249 is what percent of 300

Answers

Try using simple examples to help you get started e.g. 1 is how many percent of 2? You probably already know that it is 50%. You can use a formula to work this out (1/2)*100=50%. So you can use this information for your question:
(249/300)*100=83%

Simplify the number using the imaginary unit i:(square root) -28

options:
a. 2(square root) -7
b. -2(square root) -7
c. i(square root) 28
d. 2i(square root) 28

Answers

We have to simplify:
√ ( - 28 )
We know that √ (-1 ) = i ( the imaginary unit )
√ ( - 28 ) = √ 28 * ( - 1 ) = i √ ( 28 ) = i √ ( 4 * 7 ) = 2 i √( 7 )
But there is not such solution among the options.
Only correct answer ( using the imaginary unit ) is:
C. i (square root) 28
 

The simplified form is 2√7i.

Hence none of the provide option correct.

To simplify the square root of -28 using the imaginary unit i, we can first express -28 as a product of a positive number and -1:

The square root of -28 is equal to the square root of 28 times the square root of -1, which simplifies to 2 times the square root of 7 times i So, the simplified expression is:

2√7i.

The correct answer is not among the options provided.

The simplified form is 2√7i.

The sum of three numbers is 2100. The first number (x) is equal to the sum of the other two (y and z) which are equal to each other. What are the three numbers (x, y, and z)? A) (1050, 525, 525) B) (1050, 524, 525) C) (1050, 526, 523) D) (1051, 525, 524)

Answers

Answer:

Let's solve the problem step-by-step:

We are given that the sum of three numbers is 2100. Let's call the first number x and the other two numbers y and z.

From the information given, we know that x = y + z, and y = z (the other two numbers are equal to each other).

Substituting y = z into x = y + z, we have x = 2z.

We are also given that the sum of the three numbers is 2100. So, we can write the equation x + y + z = 2100.

Substituting x = 2z and y = z, we have 2z + z + z = 2100.

Simplifying the equation, we have 4z = 2100.

Dividing both sides of the equation by 4, we find z = 525.

Substituting z = 525 back into y = z, we find y = 525.

Finally, substituting z = 525 and y = 525 back into x = 2z, we find x = 1050.

Therefore, the three numbers are x = 1050, y = 525, and z = 525.

Among the options provided, the correct answer is A) (1050, 525, 525).

Convert from radian measure to degree measure: 3pi

Answers

To convert from radians to degrees, always multiply by 180/pi

3pi*180/pi
The pi's cancel out and you are left with 3*180 or 540°

Hope this helps
There are 2 PI radians in 360 degrees, so 3 PI radians = 1.5 circles = 360 + 180 = 540 degrees
