Answer:

The first picture is A

The second picture is 21.8

The third picture is 20

The fourth picture is B

4x + 8x = 180

12x = 180

x = 15

90 - 68.2 = 21.8

7x + 10 = 150

7x = 140

x = 20

Angle A = 63

180 - 63 = 117

topjm [15]

Answer:

10.5 %

Step-by-step explanation:

Here .

let the Cost Price be 'x'

the..

by the question..

the marked price was fixed to make 30% profit

then..

the marked price will be

x+ 30% of x

= x + 30/100 × x

=x+ 0.3x

=1.3x

soo .. the marked price is 1.3x

now.. after allowing 15% discount..

the selling price will be

1.3x - 15% of 1.3x

= 1.3x - 0.195x

= 1.105x

thank you...

plzz mark me brainliest now

now..

profit made = 1.105x-x

= 0.105x

soo .

in percentage..

profit percent = profit/cp × 100%

= 0.105x/x × 100%

= 10.5 %

HELP WILL NAME BRAINLIEST: <br> Describe and correct the error.
Aleksandr-060686 [28]

Answer:

It should be congruent by the AAS congruence theorem

Step-by-step explanation:

The error is in the congruence theorem.

We know that the 2 angles are congruent and one of the sides are congruent. This means that it can either be congruent by ASA or AAS.

It is actually congruent by AAS because it include two angles and the side is opposite of one of the angles.
