Answer:
a. 140 in²
Step-by-step explanation:
Find the area of triangle
1/2×10×6 = 30
The area of rectangle
10×11 = 110
Total of area = 30 + 110
= 140 in²
The angle of elevation is 26.565 (3dp)
let h be the end height of the ramp above
the ground , l be the length of the ramp and
the angle of elevation is (30)
i'm not sure, sorry
Answer: y = 1/2x + 3
Step-by-step explanation:
Use the equation y=mx +b
Find the slope (m) of the line by finding the difference in y over the difference in x. Or "rise over run".
The y-intercept (b) is 3 (when x is zero, it is y).
