The definition of the interior angles of a triangle states that
interior angles of a triangle add up to 180º.
This means we can find the measure of <CED:
<C
ED + <E
CD + <C
DE = 180º
<C
ED = 180º - <E
CD - <C
DE
<C
ED = 180º - 43º - 35º
<CED = 102º
By the definition of vertical angles states that a pair of vertical angles are congruent.
This means <C
ED = <A
EB
If <C
ED = 102º
Then
<AEB = 102º
By definition of the interior angles of triangles:
<AEB + <EBA + <BAE = 180º
<AEB = 102º
<EBA = 18º
102º + 18º + <BAE(<A) = 180º
<BAE = 180º - 102º - 18º
<BAE = 60º
<BAE is another way to say <A

m∠A = 60º</span>
Answer:
MN=4
Step-by-step explanation:
LM+MN=LN
4x+2+3x-5=5x+3
7x-5x=3+3
2x=6
x=3
MN=3x-5
MN=9-5=4
MN=4
Answer:
2x-5
Step-by-step explanation:
f(g(x) means stick g(x) into f(x) in place of x
f(x) = 2x+1
f(g(x) ) = 2(g(x)) +1
and we know that g(x) = x-3
so replace g(x) with x-3
f(g(x) ) = 2(x-3) +1
Distribute
f(g(x)) = 2x-6+1
= 2x-5
