Answer:

Step-by-step explanation:

This is a special type of right triangle called a 45 45 90

The sides have length a and the hypotenuse has length a* sqrt(2)

a = 7 sqrt(2)

the hypotenuse has length x

x = 7 sqrt(2) * sqrt(2)

x = 7 *2

x = 14

I have a problem -3x-7=-13. When isolating x I divide x by -3 then divide -13 by -3 correct?

rosijanka [135]

Hello!

no, that is not the correct way to isolate x. you were somewhat on the right track however.

here's the correct way:

add 7 to both sides to get -3x = -6

then divide both sides by -3 to get x = 2

I hope this helps, and have a nice day!

Use the Exterior Angle Inequality Theorem to list all of the angles that measure less than the measure of Angle 1

11111nata11111 [884]

Answer:

Step-by-step explanation:

Since, angle 1 is an exterior angle of ΔABE,

m∠1 > m∠3 and m∠4

Since, angle 1 is an exterior angle of ΔABD,

m∠1 > m∠5

Since, angle 1 is an exterior angle of ΔABC,

m∠1 > m∠7 and m∠8

Therefore, ∠1 is greater than ∠3, ∠5, ∠7 and ∠8.
