Hi!
So the angles make a right angle which is also known as a complementary angle.
What you want to do is set both terms equal to 90
11x + 4x = 90
15x = 90
divide by 15
x = 6
now multiply 6 by 4 because you want to know whata angle 3 is
6*4 = 24
24 degrees is your answer!
Hope this helps!

Answer:
$3100
Step-by-step explanation:
Step one:
given data
Principal = $2500
rate = 1.2%
time = 20 years
Step two:
The simple interest is expressed as
SI= PRT/100
substitute
SI= 2500*1.2*20/100
SI= $600
The account balance after 20 years is
= principal + Simple interest
= 2500+600
= $3100
