Find The Value Of X. Show Your Work.Congruent Triangle

Answers

Answer 1

Answer:

x = 3

Step-by-step explanation:

exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles

97 + x = 64 + 27

x = 97 - 64 - 27 = 6

Answer 2

Answer: x=-6

you know that the interior angles of a triangle equal 180°. so lets find the remaining angle measure

64 + 27 = 91

180 - 91 = 89

so 89 is the third interior angle of the triangle. now let's find the exterior angle.

you know that the extended angle is supplementary; which means it will equal 180° as well. so lets add the third interior angle we just found and let's add it to the unknown expression:

89 + 97 + x = 180

186 + x = 180

-186        -186

x = -6

now it might seem wrong because x is negative and it feels like it should be positive. but let's check our answer.

64+27+89 does equal 180

and 97+(-6)+89 does equal 180

i hope this helps!

Step-by-step explanation:

There are 3 stars for every 7 circles, thus the ratio is 3:7.

Answer:

3 : 7.

Step-by-step explanation:

For every 3 stars, there are 7 circles. If 3 stars is written first, you'll need to write 3 first in your answer, and 7 second.

Evaluate the expression.
131 +-5

Answers

131+-5 is equal to 126
To make it less confusing it’s just 131-5

Answer:

126

Step-by-step explanation:

131 + - 5 can either be;

131 + 5 = 136

131 - 5 = 126

The question is probably asking what is 131 plus negative 5, hence the correct equation is; 131 - 5, and the correct answer is 126.

A team of seven workers started a job, which can be done in 11 days. On the morning of the fourth day, several people left the team. The rest of the team finished the job in 14 days. How many people left the team?

Let x be the number of people who left the team.
(Hint: Focus on the work left after several workers left. )

Answers

Answer:

3 people left

Step-by-step explanation:

The job can be completed by 7 people in 11 daysThe job is equivalent of 7*11 = 77 people*days

After 3 days, job left:

(11 - 3)*7 =  56 people*days

This was completed by 7 - x people as x people left

Time needed was 14 days, we have new equation:

14(7 - x) = 567 - x = 4x = 7 - 4x = 3

As we found, 3 people left

Using two or more complete sentences, describe how you can find a vector parallel to B = (-2,3) .

Answers

Answer:

To find a vector parallel to B, such vector must be a scalar multiple of B.

Step-by-step explanation:

Two non-zero vectors are parallel if they are scalar multiples of one another.

A vector parallel to B must be a scalar multiple of B.

let the vector parallel to B be A, then their scalar multiple is given as;

A = kB

A = k(-2, 3)

where;

k is scalar

Thus, to find a vector parallel to B, such vector must be a scalar multiple of B.
