83+105+37= 225
360-225= 135
This is assuming that the figure is a parallelogram whose angles all equal 360 degrees. So your answer is angle I equals 135 degrees.
If it’s for all of them, starting with number 4, you need to find the common denominator.whatever you times the bottom by, you’ll times the top by. 4 and 7 both can turn into 28 if you multiply the 4 by 7 and the 7 by 4. Now, you multiply the 5 by 4 =20 and the 3 by 7 =21. The fractions turn to 9 and 20 over 28 minus 3 and 21 over 28.
Answer:
susan´s age=4
jack´s age=31
Step-by-step explanation:
Hello!
To solve the first part of this problem we must propose a system of equations of 2 x2, that is to say two equations with two unknowns where
J = is the age of jack
S = susan's age
with the above the following two equations are inferred
ecuation 1
J=S+27
ecuation 2
(J+5)=4(s+5)
J=4S+20-5
J=4S+15
now to solve we subtract equation 1 from equation 2 as follows
J=4S + 15
-
J=S + 27
___________
0=4S-S+15-27
0=3S-12
susan is 4 years old
now we use the ecuation number 1
J=S+27
J=4+27=31
jack is 31 years old
b.
Finally, to verify that the answer is correct, we replace the ages of jack and susan in equation 2.
(J+5)=4(s+5)
(31+5)=4(4+5)
36=36
as the equation is the same means that our answer is correct
m=11
Step-by-step explanation:
the top side is 4, so that means the bottom side will also be 4, add them both, you get 8, 30-8 = 22, 22/2 = 11, m=11
