Find a solution to 3cos(θ)=−0.862 in radians

Mathematics
1 answer:
eimsori [14]3 years ago
7 0
3cos(\theta) = -0.862
\frac{3cos(\theta)}{3} = \frac{-0.862}{3}
cos(\theta) = -\frac{431}{1500}
cos^{-1}[cos(\theta)] = cos^{-1}(-\frac{431}{1500})
\theta = 106.6983737\°
\theta = 1.86223792^{r}

Reflect triangle stu across line st which of these is a valid reason why the image u will coincide with j
hjlf

Answer:

4. None of the above

Step-by-step explanation:

Reflection is a type of transformation that can be used to change the orientation of a given figure or shape without changing it size and shape.

When triangle STU is reflected across ST, the image U coincides with J because the two are on the opposite side and at the same distance from ST. Therefore, J is like the image of U.

Find the volume of the prism.
umka21 [38]

Answer:

C = 210cm^3

Step-by-step explanation:

We can get an estamate when we use the equation L x H x W = x/2

This shows 8 x 8 x 7,  then divide by 2 = 224cm^3

The reason it is slightly less could be the facts the teachers want you to remember this one.

For right side prism the equation is (1/2)b x h x  H

which means;

The volume of a triangular prism can be found by multiplying the base times the height. Both of the pictures of the Triangular prisms below illustrate the same formula. The formula, in general, is the area of the base (the red triangle in the picture on the right) times the height,h.

We use the side and base that surrounds the right side as (1/2)base and as side to find area then use the H as the height being the 7.
