8500-6460= 2040
2040/12=170
170*x=8500
X=50
He paid 170 a month. It took him 50 months (4.16 years) to pay off his debt
The given triangle is a right angle .
In this triangle for angle A side AC is adjacent side ,BC is opposite side and AB is hypotenuse.
Sin of any angle is the ratio of opposite and hypotenuse .

Substituting the values of opposite and hypotenuse
SinA=
Answer:
20mm
Since it a equilateral triangle we know that there is 3 sides and all of them are euqal. Therefore, 60/3 =20 meaning each side is 20mm.
Step-by-step explanation:
The longest side of a triangle must be less than the sum of the shorter sides.
If 8 and 12 are the shorter sides, and c is the longest side, then:
c < 8 + 12
c < 20
If c and 8 are the shorter sides, and 12 is the longest side then:
12 < c + 8
4 < c
The range of possible lengths for the third side is:
4 < c < 20
Answer:
1. 3-4-5 method
2. Rope method
3. Optical square method
Step-by-step explanation:
1. You'll need a measuring tape, two range poles, pegs, and three people.
The first person holds the zero mark between their thumbs and fingers, the second person holds the 3m mark on the tape between their thumbs and fingers, and the third person holds the 8m. When all sides of the rope are stretched, a triangle is created, and an angle near one is a right angle.
2. Wrap one loop of the rope around peg A with a peg through the other loop, draw a circle on the ground, place pegs B and C where the circle crosses the base line, and place peg D half way between pegs B and C, allowing pegs D and A to form lines perpendicular to the base line, forming a right angle.
3. Single and double prismatic squares are basic devices used to measure correct angles.
