Answer:
41.802 feet
Step-by-step explanation:
Given that a 92 ft path cuts diagonally from Mateo St. to Cove St. It makes an angle of 68° with Cove St. and an angle of 34° with Mateo St.
We can visualize a triangle formed by the three streets One side is 92 feet.
Angle opposite 92 feet = 
Let x be length of Cove st and y length of Mateo st.
Using sine angle for triangles,

Simplify to get
x=52.595
y=87.207
Distance saved= 
Answer:
For number 5 . a= 3 and b = -1
Answer:

Step-by-step explanation:
By definition, the absolute error is defined as:

Where:
: is the error
: is the approximate value
: is the exact value
In this problem the approximate value was 100 and the exact value was 75. Then we substitute these values in the formula to find the error.

I = prt
420 = 7000 x .02 x t
420 = 140 x t
420/140 = 140 x t /140
t = 3 years
