What is the length of AC?

Mathematics
1 answer:
Otrada [13]2 years ago
7 0

Answer:

Length of AC = <u>12units</u>.

Step-by-step explanation:

\sf\large{\star Given:-}

  • Hypotenuse of the triangle = \sf\pink{10\:units.}
  • Height of the triangle = \sf\pink{8 \: units.}

\sf\large{\star To\: Find:-}

\rightarrow Base of the triangle.

\sf\large{\star Solution:-}

\rightarrowAs we know that,

Pythagoras Theorem:

\sf\blue{Hypotenuse^2\:=\: Height^2+Base^2}

So, In triangle ABD by putting the value of hypotenuse and height in this formula we get,

\rightarrow\sf{10^2\:=\: 8^2 + Base^2}

\rightarrow\sf{100\:=\: 64 + Base^2}

\rightarrow\sf{100-64\:=\:  Base^2}

\rightarrow\sf{36\:=\:  Base^2}

\rightarrow\sf{\sqrt{36}\:=\:  Base}

\rightarrow\sf{6\:=\:  Base}

Since, it is given that BD is the perpendicular bisector of AC so length of AC will be doubled.

Therefore, length of AC of the given triangle = \sf\purple{12units.}

a survey was taken of children between the ages 7 and 12. let A be the event that the person rides the bus to school, and let B
galben [10]

Answer:

The statement is true about whether A and B are independent eventa is fourth option:

A and B are not independent events because P(A/B)=0.375 and P(A)=0.25

Step-by-step explanation:

Let A be the event that the person rides the bus to school, then:

P(A)=75/300

P(A)=0.25

Let B be the event that the person has 3 or more siblings, then:

P(B)=24/300

P(B)=0.25


P(A/B)=9/24

P(A/B)=0.375


Like P(A/B)=0.375 is different to P(A)=0.25 the events are not independent


Answer. Fourth option:

A and B are not independent events because P(A/B)=0.375 and P(A)=0.25

I need serious help with this equation.​
garri49 [273]

Answer:

First, it’s already telling you that you need to find d, which is the opposite of degree 59. This means you have to do the exact thing for degree 37. Since it’s already telling you to use sine, you need to look at the opposite side of 37 which is 98.4.

So ? is 98.4

Now, you need to find sin 59 / d.

First, plug in sin 98.4 sin (37) in your calculator (make sure it’s in degree setting)

The result is 59.2.

Now, 59.2 = sin 59 / d.

Switch sides like this: d = 59.2 sin (37)

And the answer is approximatley d = 35.6

? = 98.4

d = 35.6

ollegr [7]

Answer:

m = 4.08

Step-by-step explanation:

The line that fits good for the given data is given by :

y = 4.08x + 63.13

We need to find the slope of the given line.

The general equation of the line is given by :

y = mx +c

Where

m is slope of the line

c is y-intercept

So, the slope of the given line is 4.08.
