Answer:

y = 148°

Step-by-step explanation:

4x - 18 = 2x + 12 (alternate exterior angles are congruent)

Collect like terms

4x - 18 = 2x + 12

4x - 2x = 18 + 12

2x = 20

Divide both sides by 2

x = 10

y = 180 - (2x + 12) (linear pair theorem)

Plug in the value of x

y = 180 - (2(10) + 12)

y = 180 - (20 + 12)

y = 148°

What are the missing side lengths for the triangle?

ser-zykov [4K]

Answer:

$BC=5\sqrt{2}$ , $AC=5\sqrt{4}$

Step-by-step explanation:

In a 45-45-90 relation triangle the two shortest sides will have equal length, meaning:

$BC=5\sqrt{2}$

To find the hypotenuse we must multiply the shortest side by $\sqrt{2}$ , both sides are equal so it doesn't matter which we multiply.

$AC=5\sqrt{2} \sqrt{2} \\AC=5\sqrt{4}$
