Answer:
Step-by-step explanation:
First, do what is inside the parentheses (PEMDAS)
29+18= 47
Now do the other parentheses
17-8=9
now add them together cuz they r inside a bigger parentheses
9+47=56
now divide by 8
56/8=7
<span>Distance formula is used to prove that line segments are congruent and the lengths are equal.
Here is the distance formula :
</span><span>sqrt [(x2-x1)^2 + (y2-y1)^2]
</span>Hence the right answer is :
<span>a. congruent sides</span>
Answer:
You should be able to prove it by saying that two of the angles are congruent because of the corresponding angles theorem.
Answer:
2x-15
Step-by-step explanation:
x+2x-15=90
3x-15=90
3x=90+15
x=105/3
the other angle is 55
