The triangle Sum Theorem says that the sum of all the angles in a triangle has to equal 180 degrees. Since all three sides (and, consequently, angles) in an equilateral triangle are the same, you can divide 180 by 3 to find the measure of any angle of an equilateral triangle (60 degrees).
Which expression is equivalent to 1/2 (2+ 3x – 6)?
3x - 5
3/2x - 5
3x – 4
3/2x - 2
The Answer Is B
Answer:
first X=8.94
second X=34
Step-by-step explanation:
5) x^2=4^2+8^2
x^2=16+64=80
x=8.94
6)x^2= 31^2+14^2
x^2=961+196
x^2=1157
x=34
