Answer:

57

Step-by-step explanation:

The bottom line of the triangle is 180 degrees. Therefore, 2y + 4y - 36 has to equal 180. So, once you solve this linear equation, you will find that y equals 36. A triangle's angles always equal a total of 180 degrees. So, x + 51 + 2y has to equal 180, as well. Since we know y, substitute in 36 for 2y. Now the equation is 51 + 72 + x = 180. Solve for x. X is 57.

Answer:

57°

Step-by-step explanation:

The angles that are at the bottom middle are on a straight line, so they must add up to 180°. In order to determine y, use the equation 180 = 2y + 4y -36. After solving for y, you should be left with 36 = y. Now, we can fill in the bottom right angle in the left triangle. This would be 36 times 2, or 72. In triangles, all angles always add up to 180°, so, we can use the equation 180 = x + 51 + 72. Once solved for x, this will leave you with 57 = x, our final answer.

Answer

Step-by-step explanation:

Law of sines: SinB/15 = SinA/BC

B = 90

A = 180-90-21=69°

BC= (15*SinA)/SinB = (15*sin69)/1 ≈ 14m

Write an equation for the following and then solve.<br> Twice a number is 8. Find the number.
Yakvenalex [24]

Answer:

The number u are looking for is 4

Step-by-step explanation:

Let X be the unknown number that we want to find.

So it becomes,

2X = 8

move 2 to the other side, so it becomes a divide

X = 8/2

X = 4

A ball is thrown into the air with an upward velocity of 80 feet per second. The function h = -16t^2 + 80t models the height h,
irakobra [83]

The ball hits the ground when the height  h(t) = 0 , so

-16t^2 + 80t = 0

-16t(t - 5) = 0

t- 5 = 0  or -16t^2 = 0 (  here t = 0 which corresponds to when ball is thrown)

t - 5 = 0 gives:-

t = 5 seconds  (answer)
