Find x in each triangle

Mathematics
2 answers:
Nimfa-mama [501]3 years ago

Answer:

x=20

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

21 ^2 + x^2 = 29^2

441+x^2 =841

Subtract 441 from each side

x^2 = 841-441

x^2 = 400

Take the square root of each side

sqrt(x^2) = sqrt(400)

x = 20

Answer:

\boxed{x = 20}

Step-by-step explanation:

<em>Hey there!</em>

Well to find x we need to use the Pythagorean Theorem, which is.

a^2 + b^2 = c^2

We have a which is 21 and 29 which is c.

(21)^2 + x^2 = (29)^2

441 + x^2 = 841

-441

x^2 = 400

x = 20

So the missing side "x" is 20.

<em>Hope this helps :)</em>

Answer:

See below

Step-by-step explanation:

To graph the line we need two points, one point is the y-intercept, the second point to be calculated.

Q7

<u>y = -3x + 6</u>

  • The y-intercept is (0, 6)

<u>Let the domain be x = 5 for the second point, then:</u>

  • y = -3*5 + 6 = -15 + 6 = -9
  • The point is (5, -9)

Connect these points to get the graph

Q8

<u>y = 4/5x - 3</u>

  • The y-intercept is (0, -3)

<u>Let the domain be x = 5 for the second point, then:</u>

  • y = 4/5*5 - 3 = 4 - 3 = 1
  • The point is (5, 1)

Connect these two points to get the graph

In a recent survey, 78% of students at Lincoln Middle School said they plan to attend a camp this summer. Write this percent as
prohojiy [21]

Answer:

<em>0.78</em>

Step-by-step explanation:

From the question, we are to represent 78% as a decimal

78%  = 78/100

78/100 = 78 * 1/100

78/100 = 78 * 0.01

78/100 = 0.78

<em>hence the percent written as a decimal is 0.78</em>
