If ∠a = 90°, find the measures of ∠b, ∠c and ∠d.

nydimaria [60]

Answer:

m∠b = 35°

m∠c = 145°

m∠ d = 35°

Step-by-step explanation:

To find m∠b, we use Definition of Supplementary Angles:

180 - (90 + 55) = 35°

To find m∠c, we also use Definition of Supplementary Angles:

180 - 35 = 145°

To find m∠d, we use Vertical Angles Theorem:

m∠b = m∠d = 35°

Which graph shows the solution the the following in

faust18 [17]

Hi there! :)

Answer:

C. Third option.

*The answer must have a positive sign and open inequality.*

Step-by-step explanation:

<h2>Lesson: Graphing Inequalities</h2>

First, add by 6 from both sides of an equation.

$4d-6+6$

And then simplify.

$4d$

Next, divide by 4 from both sides of an equation.

$\frac{4d}{4}$

And finally, simplify and solve.

$24/4=6$

$24/6=4$

You can also multiply by the numbers.

$6*4=24$

$4*6=24$

Answer: $d$

The arrow must go to the left, and it should be open inequality.

Hope this helps!

Thanks!

Have a great day!
