You memorize it. Or you could do 13 times 3 and add 130
ln isosceles triangle both sides are equal and the total of all the angles in a triangle is 180 degree so the third angle will be
[180-(79+79)] degrees
=22degrees
Answer: 30y - 25b +5
Step-by-step explanation:
(look at attachment image fir explanation)
We know that
<span>To divide two fractions, they multiply "in cross". This is: the numerator of the first fraction by the denominator of the second fraction, thus we get the numerator. To obtain the denominator, we have to multiply the denominator of the first fraction by the numerator of the second fraction</span><span>
</span>Division of an integer by a fraction or vice versa <span>The unit is put as denominator to the whole and divided as a fraction</span>
we have that
1) 6/(1/2)=6*2/1=12/1=12
2)4/(1/4)=4*4/1=16/1=16
3)5/(1/3)=5*3/1=15/1=15
4)(1/2)/6=1/(6*2)=1/12
5)(1/5)/2=1/(5*2)=1/10
6)(1/8)/3=1/(8*3)=1/24
7)(1/7)/8=1/(7*8)=1/56
8)5/(1/5)=5*5/1=25/1=25
9)(1/3)/9=1/(3*9)=1/27
10)(1/4)/8=1/(4*8)=1/32
11)6/(1/7)=6*7/1=42/1=42
12)(1/6)/5=1/(6*5)=1/30
