10 sin A + 16 = 3 sin A 9
Answer:
I wish I could help you but I havent learned any of that.
Step-by-step explanation:
Seeing as how its isocoles, the boytom two angles combine to 84 degrees. leaving 276 degrees in the upper angles or 138 degrees to each angle. c= 276 and w=59
The exterior angle is ∠3 and ∠BAC is 78°
Step-by-step explanation:
An exterior angle is one formed by one side of a triangle and extension of an adjacent side of the triangle.The sum of two non-adjacent interior angles will equal the measure of the exterior angle of the triangle.
In finding the value of ∠BAC first find ∠BCA (180°-113°=67°) ⇒sum of angles formed in a straight line add up to 180°
∠BAC= 180°-(∠ABC +∠BCA)⇒sum of angles in a triangle
∠BAC=180°-(35°+67°)
∠BAC=180°-102°=78°
