If the triangle is a right triangle, the pythagorean theorem would work
since it doesn’t, the triangle is NOT A RIGHT TRIANGLE
(see attached pic for work :))
Answer:
yes its b
Step-by-step explanation:
Answer:
(D)
.
Step-by-step explanation:
The diagram is attached below:
Theorem: An exterior angle of a triangle is equal to the sum of the opposite interior angles.
The exterior angle is the angle formed by the third side and a straight line which forms a supplementary angle with the third interior angle.
In the diagram:
are opposite interior angles.
The third angle is ![\angle BAF](https://tex.z-dn.net/?f=%5Cangle%20BAF)
The angle which forms a supplementary angle with
is
.
Therefore, the exterior angle of triangle ABF is
.
In order to find scientific notation you have to move the decimal (which is located at the end of the number in the case) where it becomes a number less than 10 but greater than 1.
(190,000.) = (1.9)
How ever many times you moved the decimal (in this case 5) will now become the exponent (whether the exponent is positive or negative will tell you whether to move left or right)
(1.90,000.)
(5)
As an end result 190,000 in scientific notation will then equal 1.9x10^5
