What are the lengths of the legs of a right triangle in which one acute angle measures 19° and the hypotenuse is 15 units long?

1 answer:

6 0

The legs of a triangle with a hypotenuse that measures 15 units long have lengths that are equal to 15 times the sine or cosine of the given angle.
leg 1 = (15 units) x (cos 19) = 14.18 units
leg 2 = (15 units) x (sin 19) = 4.88 units
The lengths of the legs are 14.18 units and 4.88 units.

Answer:

Multiples [10] - 10, 20, 30, 40, 50

Multiples [11] - 11, 22, 33, 44, and 55

Find the Even numbers of these multiples

Multiples [10]

- 10 = Even
- 20 = Even
- 30 = Not Even
- 40 = Even
- 50 = Not Even

10 × 1 = 10
10 × 2 = 20
10 × 3 = 30
10 × 4 = 40
10 × 5 = 50

Multiples [11]

- 11 = Not Even
- 22 = Even
- 33 = Not Even
- 44 = Even
- 55 = Not Even

11 × 1 = 11
11 × 2 = 22
11 × 3 = 33
11 × 4 = 44
11 × 5 = 55
11 × 6 = 66
11 × 7 = 77
11 × 8 = 88
11 × 9 = 99

Show answer in lowest terms. 25/75+ 25/125=

Anit [1.1K]

Hi Jujub! To find the answer in lowest terms, first you have to find the lowest common denominator. To find this, find the lowest common multiple of 75 and 125, which is 375. Now, to make the common denominator, you have to make equivalent fractions. 375 ÷ 75 = 5, and 5 × 25 = 125. So the new fraction is 125/375. Now the same thing for 25/125. 375 ÷ 125 = 3, and 3 × 25 is 75. So the new fraction is 75/375. Now add the new fractions:
125/375 + 75/375 = 200/375

This answer can be simplified to 8/15.

Jimmy’s new cell phone cost him $49.99 when he signed a 2 year plan, which was 75% off the original place. What was the original

Sati [7]

If Jimmy's new cell cost him $49.99 with a 75% discount, then $49.99 is 100%−75%=25% of the original price.

The original price of the cell phone was $199.96.

Is the equation -x=1-y and 2+y=x+1 coincident, intersecting, or parallel

yarga [219]

$\bf x=1-y\implies x+y=1\implies y=-x+1\\\\
-------------------------------\\\\
2+y=x+1\implies y=x+1-2\implies y=x-1$

notice the equations in slope-intercept form, the first one has a slope of -1, the second one has a slope of 1.

if the slopes are equal, and the constant is different, they lines are parallel.

if the slopes are equal, and the constant is the same the equations are exactly the same thing, and the lines are coincident, on slapped on top of the other.

if the slopes differ, like here, then they have a solution, where they intersect.
