Answer:
if u ll v then this angel is the twin of the one below and is 180-72
Step-by-step explanation:
Answer:
t = 8°
Step-by-step explanation:
We know that the sum of all the angles in a triangle is equal to 180°
Let's set up our equation => 18t + 36 = 180
Subtract 36 from both sides
18t = 144
t = 8
Thus, we have our answer
Let's solve your equation step-by-step.
25812−4.2d=31.311−5.5d
Step 1: Simplify both sides of the equation.
25812−4.2d=31.311−5.5d
25812+−4.2d=31.311+−5.5d
−4.2d+25812=−5.5d+31.311
Step 2: Add 5.5d to both sides.
−4.2d+25812+5.5d=−5.5d+31.311+5.5d
1.3d+25812=31.311
Step 3: Subtract 25812 from both sides.
1.3d+25812−25812=31.311−25812
1.3d=−25780.689
Step 4: Divide both sides by 1.3.
1.3d
1.3
=
−25780.689
1.3

We have
x² + 24x = 17 (1)
Note that
(x + 12)² = x² + 24x + 144
By adding 144 to the left side of equation (1), it becomes a perfect square.
Therefore
x² + 24x = (x+12)² - 144 (2)
Substitute (2) into (1).
(x + 12)² - 144 = 17
(x + 12)² = 17 +144
(x + 12)² = 161
Answer:
We added 144 to the left side of equation (1) in order to make it a perfect square.
