Calculate m∠adc. round to the nearest tenth.

Measure of ∠ADC = 22.62°

Step-by-step explanation:

Firstly, we have right triangle ABC with AB = 12 cm and BC = 5 cm.

'Pythagoras Theorem' states that 'The sum of squares of the length of the sides in a right triangle is equal to the square of the length of the hypotenuse'.

That is,

i.e.

i.e.

i.e.

i.e.

As, the length of the hypotenuse cannot be negative.

So, we get, AC = 13 cm.

Further, we have a right triangle ACD with perpendicular = AC = 13 cm and hypotenuse = AD = 33.8 cm.

As we know, 'In a right angled triangle, the angles and sides can be written in trigonometric forms'.

That is,

i.e.

i.e.

i.e.

i.e.

Thus, the measure of ∠ADC = 22.62°

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.
