What is the value of x?Two lines, labeled m and n, that are parallel to each other. A transversal, labeled t, passes through lines m and n. Four angles are created by transversal t at each intersection with lines m and n. The angle in the lower left corner on line m is labeled x degrees, and the angle in the upper right corner on line n is labeled 48 degrees.

Answers

x = 180 - 48
x = 132

This happens because of alternate angles in parallel lines.

What is Pythagoras theorem?

It is the most important theorem of mathematics, which tells us the relationship between sides of the right angle triangle, which are known as Base(A), Height(B), Hypotenuse(H).

Pythagoras theorem,

H² = A² + B²

Given that,

Ladder = 10 foot

Bottom of ladder = 4 feet away from the bottom of tree

H² = A² + B²

10² = A² + 4²

A = 9.16

Therefore, the top of the ladder reach upto 9.2 feet high.

$4i( (1)/(2)i)^2(-2i)^2$

Answers

we know that i=√-1
so we do pemdas
$(1)/(2) i$ = $( √(-1) )/(2)$
exponents
$( ( √(-1) )/(2) )^(2)= (( √(-1) )^(2))/(2^(2))$ = $(-1)/(4)$
then $(-2i)^(2)$ =-2 times -2 times i times i=4 times -1=-4
now we have

$4i( (-1)/(4) )(-4)$ = $( (-4i)/(4) )(-4)$ = $( -i)(-4)$ =4i=aprox 4√-1

the answer is 4i
