Answer:
Option C is correct.
Ratio of longer leg to hypotenuse is;
Step-by-step explanation:
This is the special right angle triangle 30°-60°-90° as shown below in the figure.
In 30°−60°−90° right triangle,
Then:
the sides are in proportion i.e,
Therefore, the ratio of the length of the longer leg to the length of its hypotenuse is:
Answer: The answer is (C)
Step-by-step explanation: As given in the question, a right-angled triangle ABC is drawn in the attached figure, where
∠A = 30°, ∠B = 90° and ∠C = 60°.
The longest leg is AB, AC is the hypotenuse and BC is the shortest leg.
To find :- AB : AC.
We have from the right-angled triangle ABC,
Thus, the correct option is (C).
2+2+=4+5= 9
y = -1/2x - 9/2
3a) Answer: 84 degrees
3x + 2(x+20)= 180 (total sum of angles in a triangle is 180 degrees)
5x+40 = 180
5x = 140
x= 28
3x= 28 x 3
= 84
x=2m−6
