Step-by-step explanation: for a triangle to be acute all three angles have to measure below 90 degrees
Answer:
Therefore the value of ∠ is °.
Therefore the value of ∠ is °.
Step-by-step explanation:
Given that,
is a triangle.
, , and ∠°
and we have to find the value of ∠.
Diagram of the Δ is shown below:
Now,
According to Law of Sine,
⇒
⇒
⇒
⇒
⇒
⇒
∴∠°
Therefore the value of ∠ is °.
In Δ,
∠∠∠° [Angle sum property]
⇒ °°∠°
⇒ ∠°
Therefore the value of ∠ is °.
