Answer:

θ = 68°

Step-by-step explanation:

The side 3 is adjacent to the angle we need to find , and we know the hypothenuse so will use the cosθ function

cos θ = adj/ hyp = 3/8

To find the angle we need to apply the inverse function cos ^(-1) and use the calculator to solve it.

θ = cos ^(-1) (3/8) = 67.97

Round to the nearest degree and will have

Answer:

68°

Step-by-step explanation:

The situation can be represented by a right triangle with the ladder as the hypotenuse and θ as the angle between the ladder and the ground.

Using the cosine ratio in the right triangle

cosθ = $\frac{adjacent}{hypotenuse}$ = $\frac{3}{8}$ , then

θ = $cos^{-1}$ ( $\frac{3}{8}$ ) ≈ 68° ( to the nearest degree )

timama [110]

Answer:

When x=2

Step-by-step explanation:

Well in the first one it tells you that 2x is 90.

In the second it's y=40x+10

So you plug 2 in as the x.

y=40(2)+10

y=80+10

y=90

Hope this helps

Point Q' is the image of Q(-7, -6) under the translation (x, y) + (x + 12, y + 8).

Lina20 [59]

Answer:

The co-ordinates of Q' is (5,2).

Step-by-step explanation:

Given:

Pre-image point

Q(-7,-6)

To find Image point Q' after following translation.

$(x,y)\rightarrow (x+12,y+8)$

Solution:

Translation rules:

Horizontal shift:

$(x,y)\rightarrow (x+k,y)$

when $K>0$ the point is translated $k$ units to the right.

when $K$ the point is translated $k$ units to the left.

Vertical shift:

$(x,y)\rightarrow (x,y+k)$

when $K>0$ the point is translated $k$ units up.

when $K$ the point is translated $k$ units down.

Given translation $(x,y)\rightarrow (x+12,y+8)$ shows the point is shifted 12 units to the right and 8 units up.

The point Q' can be given as:

Q'= $(-7+12,-6+8)=(5,2)$

So, the co-ordinates of Q' is (5,2). (Answer)
