Answer: 66 degrees
Step-by-step explanation:
Sum of the angle measures is 180, so:
71 + x + 49 + x + 72 = 180
2x + 192 = 180
2x = -12
x = -6
Meaning the measure of angle A = -6 + 72 = 66 deg.
Answer:
y =0
Step-by-step explanation:
From the equation;
8³ × 8⁻⁵×8^y = 8⁻²= 1/8²
From the laws of indices;
aⁿ×aⁿ = a^2n
Therefore;
8³ × 8⁻⁵×8^y = 8^(3+-5+y)
8^(-2+y) = 8^-2 ; but the bases are the same and thus the exponents are the same;
-2 + y = -2
y = 0
Answer:
15
Step-by-step explanation:
var a = 3
then a= 3
var b = 5
then b = 5
a ( a new variable ) = a * b = 3 * 5
You said that 'A is 30' right there in the equation
so it would be
Xsquared=30
Answer:
No solution
Step-by-step explanation:
7x - 3 = 7 + 7x
Subtract 7x from both sides of the equation.
7
x
−3−7x=7 rewrite as
7x-7x-3=7
-3=7
