Determine if the triangles are congruent.

Mathematics
1 answer:
xenn [34]3 years ago

Answer:

Answer to number 3:

Yes, because these two are similar triangles for sure so all their respective angles are equal in measure, and two pairs of sides are congruent to each other, so the third one must be congruent too.

The sine of angle θ is 0.3.<br><br> What is cos(θ)?
Sergio [31]

The answer:

\sqrt{9}1 /10

Explanation to your question:

Since the sin of theta is 0.3, we can reasonably deduct that the opposite side to theta has a ration of 3 to 10 to that of the hypotenuse. Thus, the adjacent side to theta, using the pythagorean theorem, will be root91. Therefore, since the cosine of theta is the adjacent/hypotenuse, we get root 91/10

The value of n from the given expression is 5.5

<h3>Solution to linear equation and fractions</h3>

Fractions are expression written as a ratio of two integers. The linear equation on the other hand has a leading degree of 1.

Given the equation below;

n/11 = 3.5/7

Simplify to have

n/11 = 1/2

Cross multiply the given result to have:

11 = 2n

Swap

2n = 11

Divide both sides by 2 to have;

2n/2 = 11/2

n = 5.5

Hence the value of n from the given expression is 5.5

elena-s [515]

Answer: 2000/25 = 80 tiles

Step-by-step explanation:

Date: s=20

equation of surface area of a cube prism: surface area = 6s*2

the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2

subtitute values: surface area = 5(20)*2

= 5(400)

surface area = 2000

area of 2 tile is 5*2 = 25 square inches

2000/25 = 80 tiles

What is the y-intercept for y+2= -3/4(x+4)
fiasKO [112]

The answer would be: -5

Heres how you solve it!

First, change the x into a 0 so it can be removed.

y+2= -3/4*4

Now with the GCF you can reduce the numbers with 4.

y+2= -3

Then move the 2 to the other side causing it to change its sign into a negative

y= -3-2

Since -3 and -2 are both negative it would be -5

y= -5

then you are left with your answer.

Hope this helps! :3
