Answer: 27, 28 and 29
Step-by-step explanation:
Since the panels take three consecutive numbers of bolts to attach to the wall, let the numbers be y, y+1 and y+2.
y+y+1+y+2 = 84
3y+3=84
3y = 84 - 3
3y = 81
y = 27
Therefore, the bolts are 27, 28 and 29 respectively
Step-by-step explanation:
82 + 76 + 42 = 200
42 out of 200 hmmm
200 / 2 = 100
42 / 2 = 21
21 out of 100 = 42 out of 200
=
21%
Answer:
What is it?
Step-by-step explanation:
Answer:
The answer is A
Step-by-step explanation:
Answer:
x = 90°
y = 40°
z = 40°
Explanation (Concepts) :
A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.
Workouts:
z + 90° + 50° = 180°
z = 180° - 90° - 50°
z = 40°
=================
x + 90° = 180°
x = 180° - 90°
x = 90°
==================
50° + 90° + y = 180°
y = 180° - 90° - 50°
y = 40°
