Y=2.5 when X=5
Y=5 when X=10

Basically 10÷5=2 so 2.5×2=5

Answer:

The value of y is 5.

Step-by-step explanation:

We have been given that y varies directly with x. Thus, we have

y=kx

Now, y is 2.5 when x is 5. Thus, we have

2.5=k(5)

Divide both sides by 5, we get

k=0.5

Now, we have to find y when x is 10.

y=0.5\times10\\\\y=5

Therefore, the value of y is 5.

Work out the area of a triangle of base 8.2m and height 5m
11Alexandr11 [23.1K]
Area of a triangle is calculated by using the formula A=1/2bh
A= 1/2 (8.2) (5)
A=1/2 (41)
A=20.5 or 20 1/2, whichever way you think your teacher wants it.

Find the measure of Angle 3.
Monica [59]

Answer:

63

Step-by-step explanation:

All the angles inside the triangle must = 180

So 180 - 62 - (angle1) = ?

Angle 1 is { 180 - 125 = 55}

180 - 62 - 55 = 63

This is another trig question I need help with. Please explain how you do it to me I would appreciate it so much!!
Irina-Kira [14]

Answer:

He stepped back 59.71 feet.

Step-by-step explanation:

Start by making 2 triangles. One has 68 degrees as the acute angle at the base of the triangle and the other has 41 degrees as the acute angle at the base of the triangle. The side opposite of said angle on both triangles will be 80, the height of the tree. You're solving for the bottom (horizontal) side for both triangles.

For the triangle with an acute base angle of 68, the formula to solve for the horizontal side is tan(68) = 80/x.

Get x by itself to get 80/tan(68) = x

x = 32.32.

For the next triangle, the equation is the same but the angle is changed to 41.

tan(41) = 80/x

80/tan(41) = x

x = 92.03

Finally, subtract the smaller distance from the larger:

92.03 - 32.32 = 59.71 steps.
