To solve this question we must first find out what is x.
X + x - 4 = 82 degrees
2x - 4 = 82
2x = 86
X = 86/2 = 43.
Here x would be 43 degrees.
We can add up the angles because we know the angle of DAC and the CAB angle add up to give 82 degrees.
The answer to the corresponding part is <Y
Answer:
B
Step-by-step explanation:
y = (x + 1)/x
xy = x + 1
xy - x = 1
x(y - 1) = 1
x = 1/(y - 1)
Interswitch variables
f^-1(x) = 1/(x - 1)
Answer:
Step-by-step explanation:
D²=290²+2030²
=290²+(290×7)²
=290²+290²×7²
=290²(1+7²)
=290²(1+49)
=290²×50
=290²×25×2
=290²×5²×2
D=290×5×√2
D=1450√2
