How do you solve this step by step?

x = -1

Step-by-step explanation:

since the 23 is positive you have to subtract it on both sides . which would give you -4x =4

then divide -4 on each side and you should get x = -1

a positive divided by a negative is always negative.

1/800 is the right answer

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
