Answer:
C. 15
Step-by-step explanation:
Small triangle is similar to larger one so we can use the similarity ratio to solve the question:
CE/CA = DE/AB
4/12 = 5/AB cross multiply expressions
4AB = 60 divide both sides by 4
AB = 15
Answer:

Step-by-step explanation:
, substitute
to x
=
or 3.75
=
= 
Vertically opposite angles are always equal.
Given angles are (8x+12)° and (3x+37)°
=> (8x+12)° = (3x + 37)°
=> 8x - 3x = 37-12
=> 5x = 25
=> x = 25/5 = 5°
Angle 1 = (8x+12)° = (8(5)+12) = 40+12 = 52°
Angle 2 = (3x + 37)° = (3(5)+37)° = 15+37 = 52°
Answer:
im kind of rusty on this math but i think the equation would be y=-5x+b i forgot how to find b tho :( im sorry
Answer:
<A = 35 degrees
Step-by-step explanation:
<A = x
<B = 2x
<C = 2x + 5
X + 2x + 2x + 5 = 180 degrees
5x + 5 = 180
5x = 180 -5
x = 175/5
x = 35
