Answer:
Step-by-step explanation:
<h3>What are the definitions?</h3>
- Obtuse triangle - the triangle with angle greater than 90°;
- Acute triangle - the triangle with all interior angles under 90°;
- Isosceles triangle - the triangle with a pair of equal sides;
- Scalene triangle - the triangle with all three sides (or angles) of different measure.
<h3>What we have?</h3>
- All sides are different and all angles are under 90°.
<h3>Which option is correct?</h3>
Answer:
A
Step-by-step explanation:
I guessed also I just took the exam
Answer:
B. f(x) is shifted left by 6 units
Step-by-step explanation:
when we talk about translations, we know they happen along the X axis, y axis or sometimes both, in this case we see that were subtracting x by six units, so we are moving left along the x axis
ways to remember this is:
-you count up x the RIGHT way going right
-you count UP y
and of cource by process of ellimination we know that decreasing X goes left and decreasing y goes down
ALSO NOTE: x always goes horizontally and y always goes vertically
Answer:
3x+30= 116° 2x=64°
Step-by-step explanation:
the angle below 2x is the same as 3x+20 so we know that 5x+20=180 so solve this
5x+20=180
5x=160
x=32
sub x into the angle equations
3(32)+20=116
2(32)=64
