Answer:
1) At least two equal sides
2) One pair of equal angles
Answer:
Slope is the 'steepness' of the line, also commonly known as rise over run (y/x)
Step-by-step explanation:
It it called an equation. Equation consist of number, symbols, and a equal sign.
To solve, first do -2 times t and -2 times 8. Your equation would look like this after: -2T+(-16)=12. Then add 16 to each side. -2T=28. Next, divide by -2. T=-14 is your answer.
Answer:
x=62
z=47
y=40
Step-by-step explanation:
Opposite angles created by two lines are equal.
x=62
31+z=78, z=47
Angles along a straight line add to 180.
x+y+z+21=180
62+y+47+31=180
y=180-140=40
