A and B are complementary angles. If m_A = (6x + 29) and m

Liono4ka [1.6K]

Answer:

m∠ $A=77$ °

Step-by-step explanation:

Complementary angles are a pair of angles whose measures have a sum of $90$ °. Since m∠ $A$ = $6x+29$ and m∠ $B$ = $x+5$ , we can write the following equation to solve for $x$ :

$6x+29+x+5=90$

Solving for $x$ , we get:

$6x+29+x+5=90$

$7x+34=90$ (Simplify LHS)

$7x+34-34=90-34$ (Subtract $34$ from both sides of the equation to isolate $x$ )

$7x=56$ (Simplify)

$\frac{7x}{7}=\frac{56}{7}$ (Divide both sides of the equation by $7$ to get rid of $x$ 's coefficient)

$x=8$

Therefore, m∠ $A=6x+29=6(8)+29=48+29=77$ °. Hope this helps!

Answer:

Option A. 36

Step-by-step explanation:

Let

x-------> the number of boys

y------> the number of girls

we know that

$x+y=42$ -----> equation A

$y=\sqrt{x}$ -----> equation B

using a graphing tool to solve the system of equations

Remember that the solution is the intersection point both graphs

The solution is the point (36,6)

see the attached figure

therefore

The number of boys is 36
