Given:
A rope tied from a tent pole to a stake in the ground forms 55 degrees angle with the ground.
The pole is 3 feet from the stake.
To find:
The length of the rope to the nearest tenth of a foot.
Solution:
First draw a diagram according to the given information as shown below.
We know that, in a right angled triangle,
In triangle ABC,
Therefore, the length of the rope is 5.2 foot.
To subtract 98.86 from 85.15, let's line them up by decimal.
98.66
-85.15
______
13.51 is the answer.

interior angles of a triangle add upto 180°.
(7x+10)+(x+20)+2x=180°
7x+10+x+20+2x=180
collecting like terms;
7x+x+2x+10+20=180
10x+30=180
10x=180-30
10x=150
10x/10=150/10
x=15°
substituting X in the angles;
7x+10=7(15)+10=115°
x+20=15+20=35°
2x=2(15)=30°
there the largest angle is 7x+10=115°
The correct answer for the question that is being presented above is this one: "D. 3 and 60."
