The answer would be -4 because when you add a positive and a negative it’s like subtracting.
Answer:55
Step-by-step explanation:
55
Let x = the unknown angle
sine of an angle is measure of the opposite leg divided by the hypotenuse.
sin x = 10/21
To now solve for x, we so the inverse of sine.
sin⁻¹(10/21) = x
Plug this into your calculator.
x ≈ 28.44 degrees. This would round down to 28 degrees, option B is your answer.
Answer:
How am I supposed to answer this? are there any answer choices or an equation im supposed to look at ?
Step-by-step explanation:
The measure of the exterior angle is equal to the sum of the remote interior angles. Overall the sum of all the angles of a triangle is 180 degrees.
As given in the question,
Two remote interior angles measure = 
Hence, the exterior angle will be 99°
Option B is correct- The exterior angle measures 99˚.
