Triangle ABC is such that AB = 3cm , BC = 4cm , angle ABC = 120 and BAC = theta : Write down in terms of theta , and expression

for angle ACB ( why is this (60-theta) and not (120-theta)? Next question asks for using the sine rule (or otherwise) show that tan theta = 2sqrt3 /(5) A diagram would be pretty cool guys

1)inside the triangule is 180º .There are 3 angules, one with 120º, theta and
angle ACB, lets call it x.

x + theta + 120 = 180
x + theta= 180-120
x + theta= 60
x= 60- theta
angle ACB= 60- theta

A football team played 90 matches. They won 37 matches.
Mekhanik [1.2K]

Answer:<em> 44 matches</em>

Step-by-step explanation:

<em>Let's take the given information</em>

<em>They won 37 matches</em>

<em>1/9th of their matches resulted in a draw</em>

<em>1/9 out of 90 is 9</em>

<em>You can take 90/9 and you will get 9</em>

<em>Now let us add 37+9 and you get 47</em>

<em>Now take 90-47</em>

<em>44 Matches lost</em>

<em>22/45 or 44/90</em>

I don’t understand helpppppooppoppppp
liraira [26]

Answer:

length is 20 and the width is 5

Step-by-step explanation:

so Area is 100

Area = width * length

legth = 4 * width

This means:

Area = width * 4 width =>  Area = 5 * width

We know that area is 100 so:

100 = 5 * width

that means width = 20, but wait didn't I say that the length is 20? Yes, remember we said length = 4 * width at the beginning, so <u>length = 20</u>.

Now we can easily calculate width as width is 4 times smaller than length, so:

<u>width = 20/4 => 5</u>

We can also test if this is correct by simply using the formula to calculate rectangle. So 5 * 20 = 100, correct!

A particular baseball player has a batting average (number of hits/number of times at bat) of 0.364. What is the probability tha
MAXImum [283]
The correct answer is option (c) <span>P(not a hit) = 0.636

</span>The batting average of the baseball player = \frac{number of hits}{number of times at bat} = 0.364

Now, the probability of occurrence of any event is say, P, the probability of not occurrence of the event is given as =  1 - P

Therefore, <span>the probability that he will not get a hit at his next at bat = 1- 0.364 = 0.636</span>

Find the value of x in this equation. 25(4x − 3) − 2x = 45 − x
Charra [1.4K]

Answer:

x=40/33

Step-by-step explanation:

Let's solve your equation step-by-step.

25(4x−3)−2x=45−x

Step 1: Simplify both sides of the equation.

25(4x−3)−2x=45−x

(25)(4x)+(25)(−3)+−2x=45+−x(Distribute)

100x+−75+−2x=45+−x

(100x+−2x)+(−75)=−x+45(Combine Like Terms)

98x+−75=−x+45

98x−75=−x+45

Step 2: Add x to both sides.

98x−75+x=−x+45+x

99x−75=45

Step 3: Add 75 to both sides.

99x−75+75=45+75

99x=120

Step 4: Divide both sides by 99.

99x

99

=

120

99

x=

40

Answer:

x=40/33
