Answer:

1. ∠C = 90°
2. ∠B = 90°
3. ∠BAD = 90°
4. ∠ADC = 90°
5. ∠EDC = 90° - 53° = 37°
6. ∠EDF = ∠DEC = 53°
7. ∠FED = 90° - 53° = 37°
8. ∠FEA = 90° - ∠FED = 90° - 37° = 53°
9. ∠EFA = 90°
10. ∠FAE = 90° - ∠FEA = 90° - 53° = 37°
11. ∠EAB = 90° - ∠FAE = 90° - 37° = 53°
12. ∠AEB = 90° - ∠EAB = 90° - 53 = 37°

Answer:

<h3><u>Let's</u><u> </u><u>understand the concept</u><u>:</u><u>-</u></h3>

Here angle B is 90°

So $\triangle ABC$ and $\triangle ABD$ Are right angled triangle

So we use Pythagoras thereon for solution

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

First in triangle ABC

perpendicular=p=8cm

Hypontenuse =h =10cm

We need to find base=b

According to Pythagoras thereon

${\boxed{\sf b^2=h^2-p^2}}$

Substitutethe values

$\longrightarrow$ $\sf b^2=10^2-p^2$

$\longrightarrow$ $\sf b={\sqrt {10^2-8^2}}$

$\longrightarrow$ $\sf b={\sqrt{100-64}}$

$\longrightarrow$ $\bf b={\sqrt {36}}$

$\longrightarrow$ $\sf b=6$

$\therefore$ $\overline{BC}=6cm$

BD=BC+CD

$\longrightarrow$ $BD=9+6$

$\longrightarrow$ $BD=15cm$

Now in $\triangle ABD$

Perpendicular=p=8cm

Base =b=15cm

We need to find Hypontenuse =AD(x)

According to Pythagoras thereon

${\boxed {\sf h^2=p^2+b^2}}$

Substitute the values

$\longrightarrow$ $\sf h^2=8^2+15^2$

$\longrightarrow$ $\sf h={\sqrt {8^2+15^2}}$

$\longrightarrow$ $\sf h={\sqrt {64+225}}$

$\longrightarrow$ $\sf h={\sqrt {289}}$

$\longrightarrow$ $\sf h=17cm$

$\therefore$ ${\underline{\boxed{\bf x=17cm}}}$

Question 2 of 5

ahrayia [7]

$Question$

Which two ratios represent quantities that are proportional?

Answer:

Hi, There! FrozenVines Here!

I'm here to help you Understand Better So Let's go-

20:24 is My Answer

Step-by-step explanation:

y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio

proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.

For example 2/5 is Equal to 4/10 this Would be A Example Of a Proportional relationship!

Divide and write in simplest form.

iren2701 [21]

Answer:

1. $\frac{3}{17}$ (3/17)

2. $\frac{3}{7}$ (3/7)

3. $\frac{45}{184}$ (45/184)

Step-by-step explanation:

1. $\frac{\frac{3}{5} }{3\frac{2}{5}}$ = $\frac{\frac{3}{5} }{\frac{17}{5}}$ = $\frac{\frac{3}{1} }{\frac{17}{1}}$ = $\frac{3}{17}$

2. $\frac{2}{4\frac{2}{3}}$ = $\frac{\frac{2}{1} }{\frac{14}{3}}$ = $\frac{2}{1} /\frac{14}{3}$ = $\frac{2}{1} *\frac{3}{14}$ = $\frac{6}{14}$ = $\frac{3}{7}$

3. $\frac{\frac{5}{4} }{5\frac{1}{9} }$ = $\frac{\frac{5}{4} }{\frac{46}{9}}$ = $\frac{5}{4}/\frac{46}{9}$ = $\frac{5}{2}/\frac{23}{9}$ = $\frac{5}{2}*\frac{9}{23}$ = $\frac{45}{184}$

Hope this helps!
