X + 47= 147
hope that helps
Any unknown number in an equation you represent with a variable
A squared +b squared= c squared
a squared+7 squared =10 squared
a squared + 49= 100
Then subtract 49 from 100 which is 51. Then your square root that number which is 7.14143
Answer:
m∠Q = 121°
m∠R = 58°
m∠S = 123°
m∠T = 58°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Create an expression for the sum of all the angles and equate it to 360, then solve for x:
∠Q + ∠T + ∠S + ∠R = 360
⇒ 2x + 5 + x + 2x + 7 + x = 360
⇒ 6x + 12 = 360
⇒ 6x = 360 - 12 = 348
⇒ x = 348 ÷ 6 = 58
So now we know that x = 58, we can calculate all the angles:
m∠Q = 2x + 5 = (2 x 58) + 5 = 121°
m∠R = x = 58°
m∠S = 2x + 7 = (2 x 58) + 7 = 123°
m∠T = x = 58°
Answer:
2/3
Step-by-step explanation:
6x + 4y = 72
-6x -6x
4y = 72 - 6x
/4 /4
y = 18 - 6/4x
y = -6/4x + 18
perpidicular slope is the opposite reciprical of the original line:
-6/4 is the slope of the line above.
4/6 or 2/3 would be the desired slope
check:
the two slopes mutplied would equal -1
-6/4 x 2/3 = -12/12 = -1
