an
expression which represents the sum of(-52 +10) and (–72 +9) in
simplest terms
If you mean .34 lbs and .13lbs, she would need 2.53
If you meant .34 and 1.3 lbs , she would need 1.36
If actually mean 34 lbs and 13lbs , Kaitlynn has way more than 3 lbs
Answer:
Step-by-step explanation:
<u>Right Triangle</u>
The figure shows a right triangle with angles 2 and 3 unknown.
The sum of the internal angles of all triangles is 180°, since one of them is 90°, then the sum of the rest of the angles is 90°. It means that:
The measures of both angles are expressed as functions of x. Substituting their values:
x+8 + 2x + 7 = 90
Simplifying:
3x + 15 = 90
Operating:
3x = 90 - 15 = 75
Solving:
x = 75 / 3 = 25
x = 25°
Now, the measure of angle 2=x+8 = 33°
X=-9
-x=9 so x=-9 since you inverse the sign
