Answer:
1 5/10+4/10= 1 9/10
Step-by-step explanation:
the answer is 1 and 9/10ths
It is (3+x) + 6y, since however you add the following you shall get <span>3 + (x + 6y)</span>
The angle of elevation is 18. 43 degrees
<h3>What is angle of elevation?</h3>
Angle of elevation can be described as an angle formed between a horizontal line and the line of sight above the line.
From the information given, we have that;
- Length of opposite side = 1 meter
- Length of adjacent side = 3 meters
- Angle of elevation = θ
Using the tangent identity, we have;
tan θ = opposite/ adjacent
tan θ = 1/ 3
Divide the values
tan θ =0. 3333
Find the tan inverse of the value to determine θ
θ = tan^-1(0. 3333)
θ = 18. 43 degrees
Hence, the value is 18. 43 degrees

Answer:
80
Step-by-step explanation:
sum of angles at a point = 360
85+2x+x+35=360
3x+120=360
3x=360-120
3x=240
x=240/3
x=80⁰
