Answer:
10 3/5
Step-by-step explanation:
6 4/5 + 3 4/5
First convert to improper fraction,
34/5 + 19/5
Then add the improper fractions,
=>53/5
Then convert improper fraction to mixed fraction,
=> 53/5 = 10 3/5
<u>Answer:</u>
<h2>
θ ≈ 81.37°</h2>
<u>Explanation:</u>
let the angle the ladder makes with the ground be θ
θ = cos⁻¹(3/20)
θ = cos⁻¹(0.15)
θ ≈ 81.37°
The answer must have to be 40
Find slope
slope for points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(-4,3), (4,5)
(5-3)/(4-(-4))=2/(4+4)=2/8=1/4
slope=1/4
y=mx+b
m=slope
b=yint
solve for yint
input a point
(4,5)
x=4
y=5
5=(1/4)4+b
5=1+b
minus 1
4=b
y=1/4x+4
