Answer:

m∠[tex]A=77[/tex]°

Step-by-step explanation:

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

[tex]6x+29+x+5=90[/tex]

Solving for [tex]x[/tex], we get:

[tex]6x+29+x+5=90[/tex]

[tex]7x+34=90[/tex] (Simplify LHS)

[tex]7x+34-34=90-34[/tex] (Subtract [tex]34[/tex] from both sides of the equation to isolate [tex]x[/tex])

[tex]7x=56[/tex] (Simplify)

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

[tex]x=8[/tex]

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

Answer:

The measurement of angle A is: 77°

Step-by-step explanation:

First of all, let us define complementary angles

The angles whose sum is 90° are called complementary angles.

Given angles are:

m∠A = 6x+29

m∠B = x+5

With respect to the definition, the sum of both angles will be 90°

Writing this mathematically we get

[tex]A+B = 90\\6x+29+x+5 = 90\\7x+34=90\\7x = 90-34\\7x = 56\\\frac{7x}{7} = \frac{56}{7}\\x = 8[/tex]

Putting the value of x in the expression for angle A

[tex]A = 6x+ 29 = 6(8)+29 =48+29\\A = 77[/tex]

Hence,

The measurement of angle A is: 77°
