The missing of this triangle is what if one angle is 90 and the other is 55
What is 35 degrees? All triangles angles = 180 degrees so add the two angle you know and subtract them from 180

5n + 20 =50
What is n = 6 First you minus 20 to both sides so that 20 is replaced with zero. What you do to one side you do to the other so 50-20 results are 5n=30 then get n by itself by dividing each side by 5 so that the side with the n on it is equal to 1n and you also divide 30 by 5 n = 6 replace n with in the original problem and you should get 50 cause now the original problem becomes 5 x6 + 20 =50
400

400
20/5 x 1/2
What is 2? Multiply these fractions the results are 20/10
Which is the same as 20 divided by ten
400
-2n + 5 <11
What is n>-3 Step 1 minus 5 from both sides of the equations results will be -2n<6. Step 2 divide both sides by negative 2 to get n alone final results n>-3. Because you divided by a negative number, the inequality sign gets changed to the other side. It is a -3 because a positive divided by or multiplied by a negative results in a negative number

5n=25
What is n = 5 because you have to divide each side by 5 to get n by itself
500
2^2[2(4+5)] x 5 /10 remember this ^ means exponent
What is 36 1st 4+5 because they are in the inner parenthesis =9 then multiply that by 2 now you have 2^2[18] x5 next do the exponent which is 2x2 that is 4. Take 4 and multiply by 18 you get 72 then you multiply that by five which is 360 and finally divide by 10 it = 36
