An angle measures 29.2° less than the measure of its supplementary angle. What is the measure of each angle?
kiruha [24]

Answer:

104.6 deg, 75.4 deg

Step-by-step explanation:

One angle measures x.

The other angle measures 29.2 deg less than x, so it measures x - 29.2.

They are supplementary angles, so the sum of their measures is 180 deg.

x + x - 29.2 = 180

2x - 29.2 = 180

2x = 209.2

x = 104.6

x - 29.2 = 75.4

Answer: 104.6 deg, 75.4 deg

Tell me how you got the it
stich3 [128]

Answer:

  x° = 67°

Step-by-step explanation:

1. The first three diagrams are showing you that opposite exterior angles are congruent. Based on that, when you are faced with opposite exterior angles in the fourth diagram, you are able to conclude they are congruent. That means x° = 67°.

2. You can determine the other angles in the figure based on linear angles being supplementary, and same-side interior angles being supplementary. After you work through all the angles, you find that x = 67.

Ghella [55]

Answer:

hints to solve each. partial answer due to lack of time, hope it helps!

Step-by-step explanation:

1)

a) solve ():

5 \sqrt{3} + 7 \sqrt{3} - 9 \sqrt{3} - 6 \sqrt{3} + 12 \sqrt{3} - 10 \sqrt{3} =

\sqrt{3} . (5 +7-9-6+12-10)

b) use \sqrt{6\\} = \sqrt{3\\}\\\\\sqrt{2\\}\\\\

c) use \sqrt{20\\} = \sqrt{4\\}\\\\\sqrt{5\\}\\\\ = 2\sqrt{5\\}\\\\

use \sqrt{8\\} = \sqrt{4\\}\\\\\sqrt{2\\}\\\\ = 2\sqrt{2\\}\\\\

2)

a) use \sqrt{30\\} = \sqrt{6}\sqrt{5}

use \sqrt{30\\} = \sqrt{6}\sqrt{4} = 2\sqrt{6}
