I need help with this.

90°

Step-by-step explanation:

The total degrees in a triangle should be 180° so add the two you have.

31+59=90 Then subtract that from what the total should be to know the missing value. 180-90=90

So angle E equals 90°

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
