Find the values of A and B in each triangle: show your work

Answers

Answer 1

Answer:

soh cah toa

to find a use sin =opp/hyp

sin 32=opp or a /hyp

sin 32*hyp=9.53

then to find b you can pythagorean theorem or just use cah or cos =adj/hyp

same process as above only using cos instead of sin

you get 15.3

then a^2+b^2=c^2

9.53^2+15.3^2=18^2 just to check or to use to find either a or b given c and either a or b

Find x for brainliest

Answers

Answer:

Step-by-step explanation:

6/(6+6) = 5/(5+5) = (3x+5)/(5x+14) = 1/2

3x+5 = 1/2*(5x+14)

6x+10 = 5x+14

x = 4

How many solutions will this equation have? 3(x -4) = 2x + x -4

The law of reflection states that when a ray of light reflects off a surface, the
angle of incidence is equal to the angle of reflection.
Ramesh places
a mirror on level
ground to
determine the height of a pole (with traffic light fired on it). He stands at a
certain distance so that he can see the top of the pole reflected from the mirror.
Ramesh’s eye level is 1.5 m above the ground. The distance of Ramesh and the
pole from the mirror are 1.8 m and 6 m respectively.
On the basis of the above information, answer any four of the following
questions:

(b) ASA
(c) SSS
(d) AA

(ii) What is the height of the pole?

13 meters. He places mirror between him and pole to see the reflection of light
in right position. What is the distance between mirror and Ramesh ?
(a) 7 metres

cómo puedo allar el valor absoluto de -4

Answers

Answer:

Step-by-step explanation:

abs(-4)=4

Answer:

Si recuerda, el valor absoluto de un número es el número "hecho positivo" al eliminar el signo menos si el número es negativo y simplemente dejar pasar el número si es positivo. Entonces, por ejemplo, el valor absoluto de -3 es 3 y el valor absoluto de 3 es 3.

You deposit $500 in a savings account that earns 2.5% interest compounded yearly what is the balance in the account after 20 years

Answers

Answer:

the balance in the account after 20 years is $819

Step-by-step explanation:

The computation of the balance in the account after 20 years is shown below:

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $500 × (1 + 2.5%)^20

= $500 × 1.025^20

= $819

Hence, the balance in the account after 20 years is $819

There are 9 flash cards with numbers from 20 to 28 written on them. Laura drew the card with 22 on it. She is about to draw another card. What is the probability that the sum of the numbers on these two cards will be a multiple of 5?

Answers

Answer:

1 /4

Step-by-step explanation:

Multiples of 5 = (5, 10, 15, 20, 25, 30, 35, 40, 45)

Numbers on card : (20,21,22,23,24,25,26,27,28)

Number on first card = 22

To have a sum which is a multiple of 5 ; number on second card must be either :

23 or 28

22 + 23 = 45

22 + 28 = 50

Since only 2 of the cards will. Result in a sum which is a multiple of 5

Required outcome = 2

Total possible outcomes = (9 - 1) = 8

Probability = required outcome / Total possible outcomes

= 2 / 8

= 1 /4

Answers

Answer: 160.82

Step-by-step explanation:

First, let’s get the area of the base. To do that, we multiply 9 times 5, which gets us 45. Next, for the two sides of the triangular prism, take 7 times 5, which is 35, and multiply that by two, getting 70. Next, for the two triangles, we have to use the triangle surface area formula, which is 1/2•base•height. So, take the base and the heigh, 9, and 6, and you get 54. Since there are two triangles, we don’t have to divide it by 2. So, we add all of our sides, 54, 70, and 45, and we get 169 sq cm.
