What ia the angle of AOC and DOE
natulia [17]

(i) Angle AOC would equal 48°, as it is vertically opposite to angle DOB and they are therefore equal.


(ii) Angle DOE would equal 42°. We can see this because angles on a straight line add up to 180°, and 90 + 48 = 138, so we can do 180 - 138 = 42°.


I hope this helps!

nignag [31]

Answer:

$46,000

Step-by-step explanation:

We just need to subtract all the annual payments from the salary to figure out her disposable income (which is the income remaining after deduction of taxes and social security charges).

So here's what we get

$60,000 - $3,000 - $5,000 - $6,000 = $46,000

A student gets 68 marks n therefore gets 85 percent total marks are?
mihalych1998 [28]

Answer:

There are 80 marks in total.

Step-by-step explanation:

Let the number of total marks be x.

The percentage score of the student can be written as the ratio

\displaystyle \frac{68}{x} = 85\%.

However,

\displaystyle 85\% = \frac{85}{100}.

Equating the two:

\displaystyle \frac{68}{x} = \frac{85}{100}.

Cross-multiply (that is: multiple both sides by 100x, the product of the two denominators) to get

85x = 68\times 100.

\displaystyle x = \frac{68\times 100}{85} = 80.

In other words, there are 80 marks in total.

PLEASE HELP!!! WILL GIVE BRAINLEST AWARD FOR MOST DESCRIPTIVE
Rashid [163]
The law of cosines states that:

c^2=a^2+b^2-2abcosC

You already have all the values for the variables with the exception of x so:

x^2=25+100-100cos60

x=√(125-100cos60)

x=√75

x≈8.66 to nearest one-hundredth...
