Answer:

x=3

Step-by-step explanation:

5(2)^x=40

Divide each side by 5

2^x = 8

Rewriting 8 as 2^3

2^x = 2^3

Pls help<br> will mark brainliest
yanalaym [24]

Answer:

1.93433

Step-by-step explanation:

Since all triangles have an interior angle sum of 180, the second angle is 45. this also means that x and y are equal. Using the pythagorean theorem, we can produce the equation 2\sqrt{14} = 2x^2. dividing both sides by two we get x^2= \sqrt{14}. when we take the square root of root 14 we get 1.934335
