Please help i need help its very URGENT

AB = 19.05

∠A = 45°

∠C = 45°

Step-by-step explanation:

To find a missing side length, Use Pythagorean Theorem

Pythagorean Theorem:  

Then fill in the dimensions given in the triangle

In this case, we're looking for b^2 so...

b^2 = 363

so the answer is approximately 19

Now in this case we already know the measure of B by the 90° angle.

so if the total is 180, then 180 - 90 = 90 then divided by 2 for the 2 missing angles = 45°

so the answer is 45°

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
