So we are just solving for R?
d = rt
d/t = rt/t
d/t = r
Simply isolate the r to one side, using the principle "what you do to one side, you must do to the other."
ANSWER: r = d/t
( d divided by t)
Hope this helps!! God bless! :)
First question’s answer:
Since angle A = Angle E
Therefore, Angle B (=x) = Angle D
B = X
D = 66
By replacement B = X = D = 66
So, B = 66
Answer is (A)
-------------
Second question’s answer:
Since Angle F = 63 & Angle C = (3X + 3)
Therefore, Angle F = Angle C
63 = (3X + 3)
Add (-3) into each side
63 + (-3) = (3X + 3) -3
3x + -3x = 0
63 + -3x = 3 + 0
63 + -3x = 3
Now, Add '-63' to each side of the equation
63 + -63 + -3x = 3 + -63
63 + -63 = 0
0 + -3x = 3 + -63
-3x = 3 + -63
3 + -63 = -60
-3x = -60
Divide each side by '-3'
x = 20
So, X angle value is 20 (X=20)
The answer is (C)
Good luck!
The value of ∠ABC is 64 degree at x = 19 degree ,therefore Yin is not right about the value of x .
<h3>What is a Triangle ?</h3>
A triangle is a polygon with three sides , angles and vertices.
It is given that
m∠ABC = (4x – 12)°
m∠ACB = (2x + 26)°
Let m∠ACB = y degree
It is asked that if x =19 degree , is the triangle equilateral
m∠ABC = (4x – 12)° = 4 *19 -12 = 64 degree
As in an equilateral triangle , the angles are all equal and equal to 60 degree.
If the value of ∠ABC is 64 degree at x = 19 degree ,therefore Yin is not right about the value of x .
