Complementary angles

Mathematics
1 answer:
lozanna [386]4 years ago
4 0

Answer:

The triangle ABC have a 90 degree angle, therefore the acute angles in A and B are complementary, if you add them the result is equal  to 90 degree.

Step-by-step explanation:

Supplementary angles are the angles that you can add and the result will be equal to 180 degrees. While the complementary angles are the ones that the addition result is 90 degrees. From your figure the addition of the angles ADC and BDC should be 180, therefore they are supplementary angles, while angles A and B are complementary, their sum should be 90.

Help how do i find the missing height of a parallelogram
WINSTONCH [101]

Answer:

To find the missing base, you simply divided the area by the given height. This will work the same way if you are looking for the height. To find the missing height, divide the area by the given base.

Step-by-step explanation:

base = 35cm, height = ? cm, and a = 700 cm^2 a = bh

700 = 35 x h

700/35 = 35 x h/35

20 = h

Therefore, the answer would be 20cm. Hope this helps! :)

Which equation represents the graph?
Kryger [21]
It's the second choice.  We have the parent graph of the absolute value function moved down only, not side to side.  So there is no x movement to be indicated inside the absolute value symbols along with the x.  When a function moves down, it is indicated by a negative in front of the number.  Our parent graph [absolute value of x] is moved down by 2.5 so we have [abs.value x] - 2.5

Please help anyone know how to do this.
stira [4]

A right angle triangle will follow Pythagorean theory where a^2(hypotenuse)= b^2+ c^2

Therefore 17^2=11^2+ c^2

289=121 + c^2

168 = c^2

c= 13 rounded to the nearest tenth
