First of all it is useful to say the notation in a triangle:
Opposite at the side a the angle is called A,
Opposite at the side b the angle is called B,
Opposite at the side c the angle is called C.
So, the Sinus Law can be written:
asinA=bsinB=csinC.
This Law is useful in all the cases SSA and NOT in the case SAS, in which the Law of Cosinus has to be used.
E.G.: we know a,b,A, then:
sinB=sinA⋅ba and so B is known;
C=180°−A−B and so C is known;
c=sinCsinB⋅b
If this is not to professional I don't know what this I'm in 9th grade and kinda have been exposed to this in books
Answer:72
Step-by-step explanation:because idk
Answer:1 1/6
Step-by-step explanation:
My bad nobody is correct because the answer would equal 5/24
5/24 is in simplest form
The fraction 5/24 is alread in the simplest form, so it isn't possible to reduce it any further.
This is a PROPER FRACTION once the absolute value of the top number or numerator (5) is smaller than the absolute value of the bottom number or denomintor (24).
The fraction 5/24 is equal to 5÷24 and can also be expressed in decimal form as 0.208333.
5. m∠C = 95°
6. m∠C = 70°
7. The other acute angle in the right triangle = 70°
8. m∠C = 70°
9. m∠C = 60° [equilateral triangle]
10. Measure of the exterior angle at ∠C = 110°
11. m∠B = 70°
12. m∠Z = 70°
<h3>What are Triangles?</h3>
A triangle is a 3-sided polygon with three sides and three angles. The sum of all its interior angles is 180 degrees. Some special triangles are:
- Isosceles triangle: has 2 equal base angles.
- Equilateral triangle: has three equal angles, each measuring 60 degrees.
- Right Triangle: Has one of its angles as 90 degrees, while the other two are acute angles.
5. m∠C = 180 - 50 - 35 [triangle sum theorem]
m∠C = 95°
6. m∠C = 180 - 25 - 85 [triangle sum theorem]
m∠C = 70°
7. The other acute angle in the right triangle = 180 - 90 - 25 [triangle sum theorem]
The other acute angle = 70°
8. m∠C = 180 - 55 - 55 [isosceles triangle]
m∠C = 70°
9. m∠C = 60° [equilateral triangle]
10. Measure of the exterior angle at ∠C = 50 + 60
Measure of the exterior angle at ∠C = 110°
11. m∠B = 115 - 45
m∠B = 70°
12. m∠Z = 180 - 35 - 75
m∠Z = 70°
