In the given question ~
Line segments BC and DE are parallel to one another therefore,
The Angles :
[ By corresponding Angle property ]
Now, in the given figure the Triangles ABC and ADE are similar to one another. by AA criteria of similarity.
since we know, The sides of similar triangles are in equal proportion, let's use the property ~
Answer:
0.01167
Step-by-step explanation:
180 - 0.669 = 89.331
complementary angle = 89.331
cos(89.331) = 0.01167
Answer:
Multiply the decimal for the percent of tax by the purchase price, then add the amount of tax to the price to find the total price.
Step-by-step explanation:
Sales tax is an amount added to a price to get the total.
We multiply by the decimal for the percent; this means we divide the percent by 100 before we multiply.
Once we multiply, this gives us the amount of sales tax. We add this to the price of the item to get the total purchase price.
here ratio is 1:8
total parts 1+8=9
so first we divide 270 by 9 which is 30
first part is 1*30 which is 30
second part is 8*30 which is 240
therefore £270 in the ratio 1/8 is 30/240
