Answer:
C: 56,72,52
Step-by-step explanation:
we know that
An acute triangle is a triangle with three angles less than 90°
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
<u><em>Verify each case</em></u>
case A) The three measures are less than 90 degrees but the sum is not equal to 180 degrees (is not a triangle)
case B) The three measures are not less than 90 degrees
case C) The three measures represent an acute triangle ( the three measures are less than 90 degrees and the sum is equal to 180 degrees)
case D) The three measures are not less than 90 degrees. This triangle represent a right triangle
I don’t know if I’m 100% correct but I got
Exact form x= 103/5
Decimal form x=20.6
Answer:
If their angles are the same, if they are proportional, if it states so
Step-by-step explanation:
I don't see the image you sent, but just naming different things that proves how triangles are similar.
Answer:
x= -1, y= 1
Step-by-step explanation:
2x + 6y = 4.........(1)
8x - 5y = 45........(2)
multiply equation (1) by 4
8x + 24y = 16......(3)
subtract equation (3) by (2)
29y = 29
y = 1
then substitute y=1 in equation (1)
2x + 6(1) = 4
solving for x
x = -2/2 = -1
