Question

Select the best equation needed to solve for x; then solve for x:

A. 2x+1=33 ; x=16
B. 2x+1=33 ; x=17
C. 2x+1+33=90 ; x = 28
D. 2x+1+33=90 ; x=56

Answer 1

Answer: C

Step-by-step explanation: a right angle is 90 degrees

2*28 = 56, 56 + 1 = 57

57 + 33 = 90

Therefore the answer is C.

Answer 2

x=28 or C

Explanation:

The graph shows a right angle which is 90 degrees

This means that the two angles seperated by line C added together will get 90 degrees.

That means the formula will be 2x+1+33=90

With that shown we can get rid of A and B

Next step is to add 33 and 1 together

This gives us 2x+34=90

Then we will move 34 to the other side by subtracting giving us 2x=90-34

Then we will subtract 90-34 which will get us 56

The equation is now 2x=56

The last step is to devide 2 from each side

This lets us get the answer x=28

Hope this helps!
