EXPLANATION
To solve this problem you need to remember that a straight line is 180°. This figure is basically a straight line split in two, so 134°+x=180°. You can also subtract 134 from 180 to get 46.

Answers

Answer:

Step-by-step explanation:

∠A + ∠B + ∠C = 180 {Angle sum property of triangle}

∠A + 65 + 55 = 180

∠A + 120 = 180

∠A = 180 - 120

∠A = 60

If two triangles are similar, then the corresponding angles of two triangles are congruent.

z = ∠A

z = 60

Solution -:

In ∆ ABC,

[tex]\angle[/tex] A + [tex]\angle[/tex] B + [tex]\angle[/tex] C = 180° .... (Angle sum property of a triangle)

Here, we have:

[tex]\angle[/tex] B = 65°

[tex]\angle[/tex] C = 55°

Substituting values,

[tex]\dashrightarrow\sf{\angle A + 65 + 55 = 180} \\ \\ \dashrightarrow\sf{\angle A + 120 = 180} \\ \\ \dashrightarrow\sf{\angle A = 180 - 120} \\ \\ \dashrightarrow{\boxed{\sf{\gray \angle A = 60 \: \bigstar}}}[/tex]

As we know that,

★ If two triangles are similar, then the corresponding sides of two triangles are congruent.

[tex]\longrightarrow\tt{z= \angle A } \\ \\ \longrightarrow{\boxed{\tt{\gray Z = 60 \: \bigstar}}}[/tex]

Answers

The calculated length of V'B' in the reflection of triangles is (c) 5

How to determine the length of V'B'

From the question, we have the following parameters that can be used in our computation:

The triangle and the image

Also, we know that the triangles are reflected

The reflection transformation is a rigid transformation

This means that

V'B' = VB

From the figures, we have

VB = 5

So, we have

V'B' = 5

Hence, the length of V'B' is (c) 5

A colony of 1,000 bacteria doubles in size every 18 minutes. What will the population be 54 minutes from now? (show steps) - will give brainliest

Answers

Answer:

3000.24

Step-by-step explanation:

We know that every 18 min, the colony grows 1000, so to make it easy, the way i do it is that i find out how much it grows per min

1000 / 18 = 55.56

Then, to find out how big it will be in 54 min, we just multiply

55.56 x 54 = 3000.24

So that will be the size of the colony in 54 min. I hope this helps :)

how does the Torah affect Jewish life today !!!!!!!
i will give brainlisttttt

Answers

Answer:

the Torah plays a big part in the lives of Jews today as it is believed to be the word of God. All Jews use the Torah to help guide them in their lives, but some Jews use the Torah more strictly than others. For example, some Orthodox Jews believe that it is important to follow every single rule in the Torah. However, Reform Jews tend to follow the rules they feel are most important and disregard some rules they see as outdated.

The significance of the Torah is seen in many ways:

It is read aloud weekly at the synagogue. It takes a year to recite the whole Torah.

The festival of Shavout celebrates God’s revelation of the Torah to Moses.

The commandments in the Torah shape the way that Jews live their lives today.

Question 10 (2 points)
Find the missing length.
a
2.1 cm
2.9 cm
I NEED HELPPPP PLSSSS ITS FOR A MASTERY TEST PLSSSS HELPPPP

Answers

Answer:

a = 2

Step-by-step explanation:

To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!

The Pythagorean Theorem states:

a^2 + b^2 = c^2

Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)

a^2 + 2.1^2 = 2.9^2

Finally, we solve our equation (hint: use the calculator if needed)

a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)

a = 2 (Now that's the final answer!)

What is the image of the point (9,7) after a rotation of 180 counterclockwise about the origin

Answers

you would just negate each value, so it would be (-9,-7). you can also double check on a calculator

The image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Rotation of a point A(x, y) 180 counterclockwise about the origin produces an image at A'(-x, -y).

Hence, the image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

What’s the volume of the prism ?

Answers

Answer:

63[tex]cm^{3}[/tex]

Step-by-step explanation:

To find the volume of this prism, all you need to do is multiply the height, the width, and the length of the prism. The height is 3, the length is 7, and the width is 3. So 3·3·7=9·7=63. Now we have to add the label, which is cm. We are multiplying 3cm by 3cm by 7cm, which makes it [tex]cm^{3}[/tex]. Now you just multiply [tex]cm^{3}[/tex] and 63 together, which gets you 63[tex]cm^{3}[/tex].

Read the following passage from Heywood Brouns The Fifty-First Dragon to answer questions 6-10.OF all the pupils at the knight school Gawaine le Cur-Hardy was among the least promising. He was tall and sturdy, but his instructors soon discovered that he lacked spirit. He would hide in the woods when the jousting class was called, although his companions and members of the faculty sought to appeal to his better nature by shouting to him to come out and break his neck like a man. Even when they told him that the lances were padded, the horses no more than ponies and the field unusually soft for late autumn, Gawaine refused to grow enthusiastic. The Headmaster and the Assistant Professor of Pleasaunce were discussing the case one spring afternoon and the Assistant Professor could see no remedy but expulsion.No, said the Headmaster, as he looked out at the purple hills which ringed the school, I think Ill train him to slay dragons.He might be killed, objected the Assistant Professor.So he might, replied the Headmaster brightly, but he added, more soberly, we must consider the greater good. We are responsible for the formation of this lads character.Are the dragons particularly bad this year? interrupted the Assistant Professor. This was characteristic. He always seemed restive when the head of the school began to talk ethics and the ideals of the institution.Ive never known them worse, replied the Headmaster. Up in the hills to the south last week they killed a number of peasants, two cows and a prize pig. And if this dry spell holds theres no telling when they may start a forest fire simply by breathing around indiscriminately.Would any refund on the tuition fee be necessary in case of an accident to young Cur-Hardy?No, the principal answered, judicially, thats all covered in the contract. But as a matter of fact he wont be killed. Before I send him up in the hills Im going to give him a magic word.Thats a good idea, said the Professor. Sometimes they work wonders.6.
