The measures of two angles have a sum of 90º if and only if the angles are complements.
if the angles are complementary they have to equal 90 otherwise they are not complementary
Answer:
is isosceles.
Step-by-step explanation:
Please have a look at the attached figure.
We are <u>given</u> the following things:
Let us try to find out and . After that we will compare them.
<u>Finding </u><u>:</u>
Side EG is a straight line so
is sum of internal and external
<u>Finding </u><u>:</u>
<u>Property of external angle:</u> External angle in a triangle is equal to the sum of two opposite internal angles of a triangle.
i.e. external =
Comparing equations (1) and (2):
It can be clearly seen that:
The two angles of are equal hence is isosceles.
Answer: b (-2,3)
Step-by-step explanation:
you substitute the x and y values in (-2,-3) for the x and y in the problem.
Answer:
12
Step-by-step explanation:
Use the pythagorean theorem (). A and b are the two legs of the triangle, and c is ALWAYS the hypotenuse. Plug in the values for a and c
