Answer:
Step-by-step explanation:
<1+<2=90 complementary
<1=4 times <2
X+4x=90
5x=90
X=18
<1=18×4=72 degrees
<2=18 degrees
<1=<3 because they are vertical
Do <3= 72
<3+<4=180 because they are supplementary
72+<4=180
<4=108 degrees
<3=72 degrees

Step-by-step explanation:
Answer:
x = 5
x = 0
Pulling out like terms :
2.1 Pull out like factors :
x2 - 5x = x • (x - 5)
Equation at the end of step 2 :
x • (x - 5) = 0
Step 3 :
Theory - Roots of a product :
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
