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°
Answer:
m∠1 = 110° and m∠2 = 70°
Step-by-step explanation:
m∠1 = 110° since vertical angles
To find m∠2, m∠1 and m∠2 must add to 180°
m∠1 + m∠2 = 180°
110° + m∠2 = 180°
m∠2 = 70°
Answer:
x = 200
Step-by-step explanation:
Given
x -
y = 30 ← substitute y = 15 into the equation
x -
× 15 = 30 , that is
x - 10 = 30 ( add 10 to both sides )
x = 40 ( multiply both sides by 5 to clear the fraction )
x = 200

Answer:
-25
Step-by-step explanation:
The following are x-values (inputs) and their y-values (outputs) that are one value apart:
(Input, output)
✅(-2, 20) and (-1, -5)
Difference between their outputs = -5 - 20 = -25
✅(-1, -5) and (0, -30)
Difference between their outputs = -30 -(-5) = -25
✅(0, -30) and (1, -55)
Difference between their outputs = -55 -(-30) = -25
✅(1, -55) and (2, -80)
Difference between their outputs = -80 -(-55) = -25
As we can see the difference of outputs for any two inputs that are one value apart = -25
