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°.

A student concluded that the inequality -3+2y<4x is equivalent to the inequality y>2x+3/2, as shown below. Describe and co

svlad2 [7]

Step-by-step explanation:

-3+2y<4x

then

2y< 4x+ 3 (add both sides with 3)

y < 2x +3/2 ( divide both sides by 2 that is positif and we do not change the sens < )

Hope you understand.
