Please help i need help its very URGENT

Answer:
AB = 19.05
∠A = 45°
∠C = 45°
Step-by-step explanation:
To find a missing side length, Use Pythagorean Theorem
Pythagorean Theorem: [tex]a^{2} +b^2=c^2[/tex]
Then fill in the dimensions given in the triangle
In this case, we're looking for b^2 so...
[tex]11^2+b^2=22^2[/tex]
[tex]121+b^2=484[/tex]
[tex]b^2=484-121[/tex]
b^2 = 363
[tex]\sqrt{363} =19.05[/tex]
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°
Answer:
AB=11SR3 or about 19.1. Angle A is 30 degrees. Angle C is 60 degrees. SR(square root).
