(sorry if these didn't help i'm a beginner and i'm in 7th grade)
D. 68
I don’t remember what formula this is called but the formula says that all angles in a triangle should add up to 180, so 75+37= 112, 180-112= 68
The sum of 5 times a number and -8:
5x - 8 = y
I think its d, because A and Cs angles make 180. And B has two equal sides that make it possible to make a triangle. Sorry i couldnt be more helpful
Answer:
8.9k
Step-by-step explanation:
We just have to add together the length of the three sides to find the perimeter of the triangle.
(1.8k-5)+(3.5+6.1k)+(k+1.5) = 1.8k-5+3.5+6.1k+k+1.5
Combine like terms.
1.8k<em>-5+3.5</em>+6.1k+k<em>+1.5</em> = 8.9k <em>+ 0 </em>
= 8.9k
