Answer:
x = 40
m∠Q = 105°
m∠R = 40°
m∠P = 35°
Step-by-step explanation:
Sum of Angles in a Triangle: 180°
Step 1: Define variables
m∠Q = 2x + 25
m∠R = x
m∠P = x - 5
Step 2: Set up equation
m∠Q + m∠R + m∠P = 180°
2x + 25 + x + x - 5 = 180°
Step 3: Solve for <em>x</em>
4x + 20 = 180
4x = 160
x = 40
Step 4: Solve for measure angles.
m∠Q = 2x + 25
m∠Q = 2(40) + 25 = 80 + 25 = 105°
m∠R = x
m∠R = 40°
m∠P = x - 5
m∠P = 40 - 5 = 35°
You can use logaritims to figure the anwser it would be: log^y X = e
Answer:
Associative Property
Step-by-step explanation:
The brackets moved, so it would be associative
Answer:
The perimeter of the larger sign : 144*1,25= 180 inches
Side of the triangle= 180/3= 60 inches
square of the height= 60^(2) - 30^(2)= 2700 ( Pythagoras' theorem)
height= square root ( 2700)= 51,96
Step-by-step explanation:
Answer:
g = 6
Step-by-step explanation:
5.2g + 10 = 2.2g + 28 (Given)
3g + 10 = 28 (Subtracted 2.2g on both sides)
3g = 18 (Subtracted 10 on both sides)
g = 6 (Divided 3 on both sides)
To check to make sure you are correct, simply substitute your answer for g:
5.2(6) + 10 = 2.2(6) + 28
31.2 + 10 = 13.2 + 28
41.2 = 41.2
You'll know you're correct if they both equal the same. In this case, the solution works.
