Answer:
a. the number of minutes jessica walked
Step-by-step explanation:
because it doesnt necessarily tell us how much minutes she walked.
Answer:
x=27
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5/3x-4/3x-1=8
5
/3
x+ −4
/3
x+−1=8
(5
/3
x+ −4
/3
x)+ (−1) =8 (Combine Like Terms)
1/3x-1 =8
1/3x=9
(1/3 x) x 3 = 3 x 9
x=27
Hi there! For this question, you need to know the ratio of sine and cosine.
- sinA = opposite/hypotenuse
- cosA = adjacent/hypotenuse
Define A = angle
opposite and adjacent side changes only if we focus on another angle.
From the picture, if we focus on angle S, the opposite would be 36. But if we focus on angle R (flip to make RT as base), see that the opposite would be 14.
Answer
- sinS = 36/42 = 6/7
- sinR = 14/42 = 1/3
- cosS = 14/42 = 1/3
- cosR = 36/42 = 6/7
The bold one is simplest form while the non-bold is non-simplest.

Hope this helps, and Happy Learning ! :)
Angle a + angle b = 180
a = 2b + 15
3b + 15 = 180
3b = 180 - 15 = 165
b = 165 divided by 3 = 55
the ratio of the two angle is 2:1 as a is twice as much as b
a is 55 x 2 + 15 = 125
b is 55
125 + 55 = 180
15,200 divided by 475 equals to 32. So, 475 fits 32 times.
