I need help with this geometry question!
Ksenya-84 [330]
Hello there! So, this is a quadrilateral and quadrilaterals equal 360 degrees. Let’s combine like terms to start off. 39x + 9 = 360. First, let’s subtract 9 from both sides to get 39x = 351. Next, divide each side y 39 to isolate the “x”. When you do that, x = 9. Now, let’s plug in the values for each, when you do, here are the final answers.

x = 9
E = 75 degrees
F = 91 degrees
G = 89 degrees
H = 105 degrees

Those are all of the angle measurements, but it wants the measurement of angle H. Therefore, that angle measurement is 105 degrees.

What is the answer to -8+5b= -6+26-9b
Slav-nsk [51]

Answer:

b=−1/14ot+2

Step-by-step explanation:

Let's solve for b.

to−8+5b=−6+26−9b

Step 1: Add 9b to both sides.

ot+5b−8+9b=−9b+20+9b

ot+14b−8=20

Step 2: Add -ot to both sides.

ot+14b−8+−ot=20+−ot

14b−8=−ot+20

Step 3: Add 8 to both sides.

14b−8+8=−ot+20+8

14b=−ot+28

Step 4: Divide both sides by 14.

14b

14

=

−ot+28

14

b=

−1
