Hey there!
Complementary angles add up to 90 degrees.
We are given
An angle of 79 degrees
and we're asked to find the complement of the angle.
So let's set up an equation:
79+x=90
where x=the unknown angle
Subtract 79 from both sides:
79-79+x=90-79
x=11
Hence, the measure of the unknown angle is

Hope everything is clear.
Let me know if you have any questions!

Answer:
BD = 21 units
Step-by-step explanation:
By applying mean ratio theorem in the given triangle ABC,

AD × CD = BD²
21 × 21 = BD²
BD² = (21)²
BD = 21
Therefore, measure of segment BD is 21 units.
Answer:
x = 9.25
y = 13.5
Step-by-step explanation:
area = 33
let length be y and width be x
2x - 5 = y
area of rectangle = length * breadth
(2x-5)(x)=33
2x²-5x=33
2x²-5x-33=0
solving quadratic equation
x = 9.25
y = 13.5
