Answer:

Step-by-step explanation:
Consider right triangle ABC with right angle C.
In this triangle,
- BA = 9.8 in
- CB = 6.3 in
- CA = 7.5 in
Write trigonometric functions:

Hence,

Answer:
d. 188.4 in
Step-by-step explanation:
i might be wrong so sorry in advance.
Answer:
13
Step-by-step explanation:
If he reads 119 pgs in 7 days that mean 119/7 = 17 he reads 17 pgs per day
next 340-119 = 221 then 221/17= 13
Form equation
y = mx + c
y = (rise/run).x + c
y = (11-1 / 3--2)x + c
y = 2x + c
11 = 2(3) + c
Find c (y-intercept)
11 - 6 = c
c = 5
Final equation of line
y = 2x + 5
Substitute given possible x-values in to find y-values
y = 2(1) + 5 = 7 (1,7)
y = 2(2) + 5 = 9 (2,9)
Therefore d is correct
It would be 9-6=3 and 9+6=17 hope this help
