Answer:
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Step-by-step explanation:
m ∠A + m ∠B = 90° Complementary angles sum = 90°
7x + 4 + 4x + 9 = 90
11x + 13 = 90
11x = 77
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Check = angle A + angle B = 90° checked
Hey!
Alright, according to P.E.M.D.A.S., the first step to solving this expression is to distribute.
<em>Original Expression :</em>

<em>New Expression {Distributed Old Expression} :</em>

Now all you have to do is simplify the parenthesis.
<em>Old Expression :</em>

<em>New Expression {Simplified} :</em>

<em>So, since the expression can no longer be simplified, the final answer is...</em>

Answer:
BD and BE are tangents to the circle
Step-by-step explanation:
Given
See attachment
Required
What does BD and BE represent?
From the attachment, we have:



The measure of angles between a tangent and the radius of a circle is always 
So, because
and AD is a radius, then BD is a tangent to circle.
Similarly,;
and AE being a radius implies that BE is a tangent to circle.
