Answer:
Step-by-step explanation: How do you find the 3rd angle of a triangle?
Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.
The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.
It can be expressed by 4(3)+4(9) you take the digit outside of the bracket and multiple by each individual digit inside the bracket.
<span>The interior angles of any polygon always add up to a constant value, which depends only on the number of sides. We use the equation as follows:
</span>sum = 180 (n−2) degrees
sum = 180 (29 - 2) degrees
sum = 4860 degrees
Hope this answers the question. Have a nice day.
