Answer:
D. 110°
Step-by-step explanation:
we know that
When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called <u><em>corresponding angles</em></u>.
When the two lines are parallel Corresponding Angles are congruent
In this problem
The transversal line is t
The two lines that are crossed by the transversal are line l and line m
Lines l and m are parallel
therefore
----> by corresponding angles
Answer:
Slope is not defined.
Step-by-step explanation:
If and are two points on a line then the slope of the line is given by
Now find the slope of the side of a square such that two adjacent vertices of a square are A(2, 3) and B(2, 8).
Take
Slope of the line
Here, is not defined.
So, slope is not defined.
Step-by-step explanation:
2x(squared)+9x+9=—1
2x(squared)+9x+9+1=0
2x(squared)+9x+10=0
multiply the coefficient of x and 10=2x10=20
2x(squared)+9x+10=0
look for two numbers that when added gives 9and when multiplied gives 20
2x(squared)+5x+4x+10=0
(2x(squared)+5x)+(4x+10)=0
find the number and letters that are common in the equations
x(2x+5)+2(2x+5)=0
(x+2) (2x+5)=0
x+2=0
collect like terms
x=0-2
x=-2
2x+5=0
collect like terms
2x=0-5
2x=-5
divide both sides by 2
2x/2=-5/2
x=-5/2
so x=-2 and -5/2
Answer:
6+ 5n
Step-by-step explanation:
I hope this helps you
-cos²x= sin²x-1
4.sinx = sin²x-1+4
sin²x-4.sinx +3=0
(sinx-3)(sinx-1)=0
sinx≠3
sinx =1
SİN90=1
