Answer:
Day 21: 810 m
Day 60: 1,200 m
Step-by-step explanation:
The amount of meters she walk everyday can be modeled as a linear function, as the rate of variation is a constant (10 m/day):
This constant (10 m/day) is the slope of the linear function.
We know one point of the linear function (D(20)=800) and the slope, so we can calculate the y-intercept:
Now, we can calculate the distance she walks by day 21 and day 60:

Answer:
SSS stands for Side Side Side triangle similarity.
SAS stands for Side Angle Side triangle similarity.
Step-by-step explanation:
1. is SSS because all the side of the two triangles are equal to each other.
2. is SAS because two side and one angle of the two triangles are equal.
3. SAS
4. SAS
5. SSS.
6. Congruent by Angle Angle but it is not said here so I would say SAS.
7. SAS
8. SSS
9. SSS
10. SSS
11. SAS
12 SSS
Answer:
6. 12.5 cm
7. 0.7241
Step-by-step explanation:
6.
You have 2 right triangles. You can use the Pythagorean theorem for each one.
a^2 + b^2 = c^2
Let y = length of vertical side between triangles.
Left triangle:
5^2 + y^2 = 13^2
25 + y^2 = 169
y^2 = 144
y = 12
Right triangle:
3.5^2 + 12^2 = x^2
12.25 + 144 = x^2
x^2 = 156.25
x = 12.5
Answer: x 12.5 cm

For <X, 2.0 ft is adj leg. 2.9 ft is hyp.
cos X = 2.0/2.9 = 0.6897
X = cos^1 0.6897 = 46.397 deg
sin X = sin 46.397 deg = 0.7241
Answer:
40
