u & v = 8

Step-by-step explanation:

This triangle is a special 45-45-90 triangle!

In a 45-45-90 triangle, to solve for the hypotenuse use the formula

h=(sidelength)*\sqrt{2}

Here we see that 8 is being multiplied by radical 2!

We can prove that 8 is the side length by using the Pythagorean Theorem!

We're given the equation T = 3x + 2.
They're asking you to find the value of T when x = 1/3, so you all need to do is replace x by its value (in this case by 1/3) in the equation.

T = 3x + 2
T = 3 * (1/3) + 2
T = 3/3 + 2
T = 1 + 2
T = 3

So when x = 1/3 , T = 3.

Hope this Helps! :D

Find the measures of the angles a-k.
denis-greek [22]
A = 54 because alternate interior angles

b = 72 because 54+54=108 and 180-108=72

c = 108 because b and c are supplemental angles

d = 72 because b and d are corresponding angles

e = 162 because 72+90=162 and definition of a straight line

f = 18 because definition of a straight line

g = 81 because definition of an isosceles triangle

h = 49.5 because vertical angles and definition of an isosceles triangle

i = 130.5 because definition of a straight line

j = 31.5 because 49.5-18=31.5

k = 99 because corresponding angles
