Answer:

20

Step-by-step explanation:

An angle bisector cuts an angle into two equal parts. So m∠ACE = m∠ECB.

m∠ACE = m∠ECB

2x − 15 = x + 5

x = 20

A pole that is 2.5 m tall casts a shadow that is 1.47 m long. At the same time, a nearby tower casts a shadow that is 36.25 m lo

Roman55 [17]

The tower is 61.65 meters tall.

<u>SOLUTION: </u>

Given that, a pole that is 2.5 m tall casts a shadow that is 1.47 m long.

At the same time, a nearby tower casts a shadow that is 36.25 m long.

We have to find height of the tower.

Now, we know that,

$2.5 \mathrm{m} \text { tall } \rightarrow 1.47 \text { long shadow }$

Then, (let it be) n meter tall $\rightarrow$ 36.25 long shadow

So, by cross multiplication method,

$\Rightarrow \frac{2.5}{1.47}=\frac{n}{36.25}$

This can be written as,

$\Rightarrow 36.25 \times 2.5=1.47 \times n \rightarrow 1.47 n=90.625 \rightarrow n=61.649 \rightarrow n=61.65 \text{ m}$

Cross multiplications steps: (To find Single Variable)

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction.
Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction.
Set the two products equal to each other.
Solve for the variable.

Find the equation of a line that passes through the point (0,1) and has a gradient of 2.

Usimov [2.4K]

Answer:

y = 2x + 1

Step-by-step explanation:

Given point (0, 1) and the slope m = 2

<u>Use point- slope form to find the equation of the line:</u>

y - y₁ = m(x - x₁)
y - 1 = 2(x - 0)
y - 1 = 2x
y = 2x + 1

What is the quotient of d − 2 √ d 4 − 5 d 3 + d + 17

Tcecarenko [31]

Answer: $d^3 - 3d^2-5$

Step-by-step explanation:

For finding the quotient of the given division,

In the long division method, we will follow the following steps.

Step 1 : Here the divisor is d-2 and dividend is $d^4-5 d^3 + d + 17$

Multiply (d-2) by $d^3$ and subtract the dividend by the resultant.

We get $-3d^3+d$

Step 2: Multiply (d-2) by $-3d^2$ and subtract the remaining dividend by the resultant.

We get $-5d^2+17$

Step 3 : Multiply (d-2) by $-5$ and subtract the remaining dividend by the resultant.

We get $7$

Since, after getting 7 it is not possible further division,

Hence, Remainder = 7,

Quotient = sum of all expression by that we multiply (d-2) = $d^3 - 3d^2-5$
