In ΔJKL, the measure of ∠L=90°, JK = 7.3 feet, and KL = 4.7 feet. Find the measure of ∠J to the nearest tenth of a degree.

40.0°

Step-by-step explanation:

Given the triangle ∆JKL with the following measure

∠L=90°, JK = 7.3 feet, and KL = 4.7 feet.

In order find the angle ∠J, we will use the concept of SOH CAH TOA.

Since we are looking for the angle ∠J, our opposite side will be the side facing the angle ∠J directly.

Hypotenuse = JK = 7.3ft

According to SOH:

Sin ∠J = Opposite/Hypotenuse

Sin∠J = 4.7/7.3

Sin∠J = 0.644

∠J = arcsin 0.644

∠J = 40.0° to the nearest tenth of a degree

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
