Answer: x= 80

Step-by-step explanation:

it’s an isoceles triangle so bottom 2 angles are 50

2. Find the magnitude and direction of the resultant vector of two forces. The first force is 250 pounds at an angle of 25 degre
Lady bird [3.3K]

Answer:

Magnitude = 220.49pounds

Direction = 16.7°

Step-by-step explanation:

Find attached the diagram obtained from the given information.

From the diagram, 25° is in the first quadrant with all positive values: x = cos25°, y = sin35°

Force for the x and y component: Fx, Fy

250(sin25, cos25) = (250sin25, 250cos25)

= [250(0.4226), 250(0.9063)]

= (105.65, 226.575)

The 250° is in the 2nd quadrant with values: x = cos250°, y = sin250°

Force for the x and y component: (Fx, Fy)

45(sin250, cos250) = (45sin250, 45cos250) = [45(-0.9397), 45(-0.3420]

= (−42.2865, -15.39)

The resultant forces for x and y components = sum of Fx in the 1st and 2nd force and, sum of Fy in the 1st and 2nd force

sum of Fx in the 1st and 2nd force = 105.65 + (−42.2865) = 63.3635

sum of Fy in the 1st and 2nd force = 226.575 + (-15.39) = 211.185

Magnitude = √[(ΣFx)² + (ΣFy)²]

= √[(63.3635)² + (211.185)²]

= √(4014.9331 + 44599.1042)

= √(48614.0373)

= 220.49pounds

Direction = arctan (ΣFx/ΣFy)

= arctan (63.3635/211.185)

= arctan(0.30)

= 16.7°

A traffic helicopter descends 114 meters to be 454 meters above ground, as illustrated in the diagram to the right. Write an equ
loris [4]

Answer:

H = h + x

h = 568 meters

Step-by-step explanation:

The helicopter descends 114 meters to be 454 meters above the ground.

Therefore, the equation which describes this situation using h as the original height will be given by  

H = h + x ....... (1)

Where H is the final height from the ground and x is the height that the helicopter ascends(Positive sign) or descends(Negative sign). (Answer)

Here, in our case, H = 454 meters and x = -114 meters.

Therefore, the original height of the helicopter from ground will be  

h = H - x = 454 - (-114) = 568 meters. (Answer)

11 more than four times a number is 39
Aliun [14]

Hello!

Your answer is: 7

(X = "<em>A number</em>")

<em>"11 more than four times a number is 39"</em> in equation form is: 4X + 11 = 39

to solve, first subtract 11 from both sides:

4X = 28

then divide both sides by 4 to get:

X = 7

I hope this helps, and have a nice day!
