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°.

salantis [7]

Answer:

The relation x^{2} +y^{2} =r^{2} is explained below.

Step-by-step explanation:

P(x, y) is a point on the circle. Q is the origin. Join PQ.

PQ is the radius.

Therefore, PQ = r

Draw PS perpendicular to the x-axis.

Now, ΔPQS is a right triangle.

By Pythagoros theorem,

PQ^{2}=PS^{2} +QS^{2}

r^{2}=x^{2} +y^{2}

x^{2} +y^{2} =r^{2}

Rainbow [258]

Answer:

Function B has the greater rate of change

Step-by-step explanation:

Function A has a slope of 1/3

Function B has a slope of 1/2

When comparing slopes, the higher value has the greater rate of change

1/2 > 1/3
