Answer:
m<U = 38degrees
Step-by-step explanation:
From the given diagram, <B = <U since both triangles are similar, hence;
Hence;
2y+2 = 3y-16
2y - 3y = -16 - 2
-y = -18
y = 18
Get m<U
m<U = 3y-16
m<U = 3(18) -16
m<U = 54 - 16
m<U = 38degrees
So for this, you'll be using the pythagorean theorem, which is 
. In this case, 10 and 24 are the legs, and AB is the hypotenuse. Our equation will be 
Firstly, solve the exponents: 
Next, combine 100 and 576: 
And lastly, square root both sides to get 
And in short, Line AB is 26 ft, or the first option.
Answer:
y=-2 x=-2
Step-by-step explanation:
y=-x-4
y=x
you can plug y in for x in the first equation by using substitution
y=-y-4
and then you solve for y
2y=-4
y=-2
so y equals -2. Since y=x, x also equals -2. Therefore
y=-2 x=-2

Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
<em>y</em><em>=</em><em>-12</em>
