Answer:
D. 35, 60, 85
Step-by-step explanation:
All angles of a triangle have to add up to 180 degrees.
35+60+85 = 180
The two numbers that are 4 units away from 0 on the number is 4 and -4.
Answer:
The equation is
Let n represent the number
4n + (-2) = 5n + 8
4n - 2 = 5n + 8
Solve for n
Group like terms
4n - 5n = 8 + 2
-1n = 10
n = 10/-1
n = -10
The number is -10
Answer:
there are 6.45 or 6.5 square cm in one square inch
Step-by-step explanation:
Answer:
Y is 90 degrees.
Step-by-step explanation:
This is an equalterial triangle which means all of the angles are the same. The angle for the upper part of the triangle is 60 as well. We can do 2x=60 because they add up to the angle which is 60. This gives us x=30. If x=30 and the other angle is 60, then the other angle has to be 90 because all triangle has an angle sum of 180. So 30 +60 + 90= 180. Hope this helps!
