Please answer please so many points not hard

option a is right.

Step-by-step explanation:

because u can also check by putting the value of x = 5.25 .it satisfies both sides.

In Heather's solution to the problem, she wrote and solved an equation.

Her work is:

Step 1: 1.08(x +9.01 +0.98 +5.01) = 21.87

Solving like terms

1.08(x+15}=21.87

dividing both side by 1.08

we get

x+15=21.87/1.08

x+15=20.25

subtracting both side by 13.9198

x=20.25-15

x=5.25

According to correction

;

Option 1st

yes,it is correct

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
