The slope for this equation is A. 1/2
For question 4, 
Question 5. Option a and question 6. Option j
Step-by-step explanation:
Step 1:
The three basic formula needed to solve these questions are:

Step 2:
Using the above formula, we solve the following values









Step 3:
For question 5, The triangle's angle = 23°, opposite side = BC inches and hypotenuse = 4 inches.

SO BC is 1.5628 inches, rounding this off to the nearest tenth, we get BC = 1.6 inches which is option a.
Step 4:
For question 6, The triangle's angle = 50°, opposite side = QR m the adjacent side = 8.1 m.

SO QR is 9.65277 meters, rounding this off to the nearest tenth, we get QR = 9.7 inches which is option j.
Answer:
113.04
Step-by-step explanation:
I flipen love this but anyways so a=start with your formula which would be
A=
so then you just subsitute which then would be
3.14*6*6
and you get
113.04
anyways i hope that helps and have a great day :)
