Answer:
x = 10 , 45 degrees.
Step-by-step explanation:
This seems a tricky one .
I guess we can use sin A + sin B = 2 sin (A+B)/2 cos (A - B) / 2
so sin 5x + sin x = 2 sin 3x cos 2x so our equation becomes
2 sin 3x cos 2x - cos 2x = 0
cos 2x ( 2 sin 3x - 1) = 0
so 2 sin 3x = 1
sin 3x = 1/2
giving 3x = 30 degrees and x = 10 degrees
or cos 2x = 0
so 2x = 90
giving x = 45 degrees.
Answer:
A) 38.62 ft
B) 92.27 ft
C) 32.59 ft
Step-by-step explanation:
A) tan10= x/185
X= 32.62 + 6ft= 38.62ft
B) tan25= x/185
X= 86.27 + 6ft= 92.27ft
C) 92.27 - 6ft= 86.27
86.27+ 32=118.27
use inverse of tan tan-1= 118.27/185 in which you get 32.59ft

We can use the formula d = rt in getting the algebraic equation for the two cars where; d = distance, r = rate, t = time.
Given:

(blue car) = 35 miles per hour

(red car) = 70 miles per hour
distance between the two towns = 140 miles

(blue car)= no. of hours the blue car travels

(red car) = no. of hours the red car travels
Linear equation for the blue car




blue car travels 4 hours from town A to town B.
Linear equation for the red car




red car travels 2 hours from town A to town B.
