Find the measures of the angles in the diagram. 20 points for all of the ones listed below
Inessa [10]
AB is a diameter of the circle, so it divides circle into two semicircles. 

Inscribed Angle Theorem:

The measure of an inscribed angle is half the measure of the intercepted arc.


An especially interesting result of the Inscribed Angle Theorem is that an angle inscribed in a semi-circle is a right angle. That's why m∠<span>AQB=m∠</span><span>ASB=m∠</span><span>ALB=m∠</span><span>ATB=m∠</span><span>ARB=90°.</span>

It is impossible to find measure of ∠<span>BWD, its measure depends on measure of a central angle ∠WDB. </span>

The price of a pedicure decreases by 4.2% from £36 on promotion.
maria [59]

A) 95.8 % of £36 will be the new price

B) The answer to part A as a decimal is £34.488

C) The new price is £34.488

<h3><u>Solution:</u></h3>

Given that the price of a pedicure decreases by 4.2% from £36 on promotion

<em><u>A) What percentage of £36 will the new price be ?</u></em>

Given that £36 is decreased by 4.2 %

New price = 36 – 4.2% of 36

\begin{array}{l}{\text { New price }=36-\frac{4.2}{100} \times 36} \\\\ {\text { New price }=36-1.512} \\\\ {\text { New price }=34.488}\end{array}

Now we have to find what percentage of £36 will the new price be

x % of 36 = 34.488

\frac{x}{100} \times 36 = 34.488\\\\x = \frac{34.488 \times 100}{36} = 95.8 \%

<em><u>B) Write your answer to part a as a decimal.</u></em>

Now, we have to find the new price in decimal form.

\begin{array}{l}{95.8 \% \times 36 \rightarrow \frac{95.8}{100} \times 36} \\\\ {\rightarrow 0.958 \times 36=34.488}\end{array}

<em><u>C) Work out the new price.</u></em>

As we calculated, the new price is £34.488
