Answer:
Step-by-step explanation:
we have a right angle triangle composited in a semi-circle we want to figure out the area of the triangle
in order to do so we need to figure out the adjacent side (height AB)
since the given triangle is a right angle triangle we can consider <u>Pythagoras</u><u> </u><u>theorem </u>given by
given that,a=21 and c=28
substitute:
move left hand side expression to right hand side and change its sign:
square root both sides:
use algebraic indentity:
simplify:
use redical property:
now to figure out the area we can consider the following formula:
remember that,h=AB=7√7 and b=BC=21 thus substitute:
simplify multiplication:
hence,
the area of the triangle is <u>1</u><u>9</u><u>4</u><u> </u> (approximately)
note: you can also use <em>horon's </em>formula but I like to keep things simple
Answer:
68 - C = m
If he completes 33 it means :
c = 33
Substituting this in the equation we have :
m > 68 - 33
m > 35
The answer is D if you need an explanation please tell me
Hope this helps!
Answer:
ABC are the marked vertices (points) of a triangle. They join each line ie) A to B= AB A to C= AC B+C=BC. We can when working on combined lines and shapes call the exterior vertices away from the triangle D and E when making reference to finding measurements of adjoining shapes/lines, but not to ABC. We can also use AB to determine the midway point as a independent or alternative use.
We usually see A on the opposite point of a right angle.
