How many unique triangles can be made where one angle 60° and another angle is an obtuse angle?

Answers

That set of requirements narrows it down to only
an infinite number of possible unique triangles.

-- One angle is 60°. That leaves 120° for the sum of the other two.

-- One angle is obtuse. It can be anything more than 90°
and less than 120°.

-- And the third angle gets whatever is left.

-- If you don't mind fractional or decimal parts of degrees, then we
already have an infinite number of possible combinations of angles.
_____________________________________

Every possible combination of angles defines a unique set of
RATIOs among the sides.

But for EVERY unique set of RATIOs, there are an infinite number of possible unique triangles that are SIMILAR to each other.

Example:

If the angles determine that the sides must be in the ratio of 1:2:3,
then the triangle can have sides of

1, 2, and 3
2, 4, and 6
3, 6, and 9
4, 8, and 12
5, 10, and 15
6, 12, and 18
7, 14, and 21
8, 16, and 24
9, 18, and 27
10, 20, and 30
.
.
etc.

These all have the SAME set of ANGLES, and the same RATIO
among the sides, but they're all different unique triangles.

8/5 ×4 5/7 so how much fruit do I have all together

Answers

7.5 is the rounded amount. So about seven and a half pieces.

7_19/35
solve
convert 4_5/7 to 33/7
now multiply that by 8/5
8/5*33/7
8*33=264
5*7=35
264/35
divide 264/35=7.542
converted to fraction it's 7_19/35

How do I transform the equations 5x+4y=8 and -2x+5y=30 so that they are in the form that y=MX+b?

Answers

4y=5x+8 5y=-2x+30 the y always goes first. then the equal sign. next is x and finally just the digit which is also known as "b".

Make y the subject for both equations:

5x + 4y = 8
4y = -5x + 8
y = -(4/5)x + 8

-2x + 5y = 30
5y = 2x + 30
y = (2/5)x + 6

There you go, both equations are in y = mx + b for :)
