Greetings!
"<span>Add or subtract. Be sure to reduce your answer: 5\6-9/20"...
To add or subtract rationals, you must find a common denominator of both fractions.
This can be done by multiplying the denominators by each other:
6*20=120
We must do the same operation to the numerators.
5*20=100
9*6=54
Now we can the subtract the rationals:
</span>100/120-54/120
<span>=100-54/120
=46/120
=23/60
Hope this helps.

Note:
The sum of all angles on a triangle will ALWAYS = 180°
So,
58 + 61 + B = 180
119 + B = 180
B = 61°
—————————————————
Method 2:
It’s an isosceles triangle where two angles are the same.
So,
B = 61°
This is not really a question but I found it funny
Answer:
solution :
in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC.
now ,
in rt angle tirangle ADC,
angleACD=45 degree, angle DAC=45 degree now,
in triangle ABD,
angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)
angle BAD+75+30=180
angle BAD=180-165 therefore,angle BAD=15
angle BAC =15+45=60
Area of triangle ABC=1/2×AB×AC×SIN 60
=1/2×10.2×14×√3/2
=61.83cm³ ans
Anwser : n = -2
Combine Like Terms
Add 4n to both sides
Subtract 3 from both sides
A = n= -2
