Multiplication all you have to.do is multiply the denominators.
Answer:18.4
Step-by-step explanation:
Answer:
.
See the diagram attached below.
Let the chords be AB and AC with common point A.
AD is the diameter. Join B with D and C with D to form two triangles.
We need to prove that AB=AC.
\begin{gathered}In\ \triangle ABD\ and \triangle ACD;\\Given\ that\ \angle BAD=\angle CAD----(condition\ 1)\\since\ AD\ is\ diameter, \angle ABD=\angle ACD = 90^0\\So\ \angle ADB=\angle ADC--------(condition\ 2)\\AD=AD\ (common\ side)-----(condition\ 3)\\ \\So\ the\ triangles\ are\ congruent\ by\ ASA\ rule.\\Hence\ AB=AC.\end{gathered}
In △ABD and△ACD;
Given that ∠BAD=∠CAD−−−−(condition 1)
since AD is diameter,∠ABD=∠ACD=90
0
So ∠ADB=∠ADC−−−−−−−−(condition 2)
AD=AD (common side)−−−−−(condition 3)
So the triangles are congruent by ASA rule.
Hence AB=AC.
"Table World" is quoting a better price
<u>Step-by-step explanation:</u>
The shop "Table World" is quoting a price of 140 inclusive of 17.5% VAT
that means 140 is the final price a customer needs to pay.
While other shop"Tables R us" is quoting a price of 120 without VAT
so we need to add VAT in the price to find out the final price
price+VAT on the price
=120+120*(17.5/100)
=120+120*0.175
=120+21
so final price =141
so comparatively "Table World" is quoting a better price
The missing reason in step 8 is the substitution property.
<h3>What is substitution property?</h3>
It should be noted that according to substitution property, if x = y, then x can be substituted for y in any equation.
When a variable is equal to another variable, then the variables can be interchangeable.
In this case, the missing reason in step 8 is the substitution property.
