B) KL= 2(JL)
C) JK= root 3 (JL)
D) JK= 2(JL)
E) JL= root 3/2 (KL)
F) JK= root 3/2 (KL)
Answer:
# Answer B is true ⇒ KL = 2(JL)
# Answer C is true ⇒ JK = √3(JL)
# Answer F is true ⇒ JK = √3/2(KL)
Step-by-step explanation:
* Lets explain the ratio between the sides of the triangle
- In Δ JKL
∵ The measure of angle J is 90°
∴ KL is the hypotenuse
∵ The measure of angle K is 30°
∴ JL is the opposite side to angle 30°
∵ The measure of angle L is 60°
∴ JK is the opposite side to the angle 60°
- There is a fact in the triangle which has angles 30° , 60° , 90°
# The length of the side opposite to the angle of measure 30° is
half the length of the hypotenuse
∵ KL is the hypotenuse
∵ JL is the opposite side to the angle of measure 30°
∴ JL = 1/2 KL OR KL = 2 JL
# The length of the side opposite to the angle of measure 60° is
√3 the length of the opposite side to the angle 30°
∵ JK is the opposite side to the angle of measure 60°
∵ JL is the opposite side to the angle of measure 30°
∴ JK = √3 JL
# The length of the side opposite to the angle of measure 60° is also
half √3 the length of the hypotenuse
∵ JK is the opposite side to the angle of measure 60°
∵ KL is the hypotenuse
∴ JK = √3/2 KL
- From the relation above
# Answer B is true ⇒ KL = 2(JL)
# Answer C is true ⇒ JK = √3(JL)
# Answer F is true ⇒ JK = √3/2(KL)
Answer:
It is a and B in C & D
Step-by-step explanation:
These are the closest answers
2/8 = 14/n =
btw :)
Answer:
n=56
Step-by-step explanation:
2/8=14/n
cross multiply
2*n=14*8
n=112/2
n=56
Answer:
n = 56
Step-by-step explanation:
Given
= ( cross- multiply )
2n = 112 ( divide both sides by 2 )
n = 56
B) 90 − (8a + 9) = (11 + 2a)
C) (11 + 2a) − 90 = (8a + 9)
D) (8a + 9) − (11 + 2a) = 90
Answer:
B
Step-by-step explanation:
Seeing the above angles we conclude that
(11+2a)+(8a+9)=90 (since they are complementary angles)
So
Subtracting (8a+9) to both sides we get
90-(8a+9)=11+2a
Answer:
The answer is B.) 90 - (8a + 9) = (11 + 2a)
Step-by-step explanation:
90 − (8a + 9) = (11 + 2a)
Complementary angles add to 90°
