A and B are complementary angles. If mA=(x+8)° and mB =(8x+1),<br> find the measure of A
Black_prince [1.1K]

Answer:

\angle A=17\textdegree

Step-by-step explanation:

We know that A and B are complementary angles. So, they must add up to 90°. As an equation:

\angle A+\angle B=90

Since we know their equations, substitute:

(x+8)+(8x+1)=90

Solve for x. Combine like terms on the left:

9x+9=90

Subtract 9 from both sides:

9x=81

Divide both sides by 9:

x=9

So, the value of x is 9.

We want to find A. So, let's use the equation for A:

\angle A=x+8

Substitute 9 for x:

\angle A=9+8

Add:

\angle A=17\textdegree

So, the measure of A is 17°.

Q # 4 anybody help me please
Marysya12 [62]

<u>Answer</u>

-5/3, -1,  0.7,  √2,   √5


<u>Explanation</u>

√5 = 2.236

-1 ⇒ this is less than 1.  

-5/3 = -1.666667    this is less than 1.  -5/3 < -1

0.7 > -1

√2 = 1.414        ⇒     √5 > √2

Arranging them from the least to the greatest;

-5/3, -1,  0.7,  √2,   √5
