Angle Relationships and Linear Equations

This video tutorial covers solving for unknown angles using equations. It begins with an introduction to the concept, followed by activities involving Tyler's angle problem and equations by Elena and Diego. The tutorial includes calculating unknown angles and concludes with homework and practice problems to reinforce learning.

What is the sum of angles A and B if they are supplementary?

• 360 degrees

• 270 degrees

• 180 degrees

• 90 degrees

Which equation correctly represents a supplementary angle relationship?

• x + 35 = 180

• x = 35

• x + 35 = 90

• x + 90 = 180

If W + 35 = 90, what type of angle is formed?

• Straight angle

• Obtuse angle

• Right angle

• Acute angle

How do you determine the value of W in a supplementary angle equation W + 124 = 180?

• Divide both sides by 124

• Multiply both sides by 124

• Subtract 124 from both sides

• Add 124 to both sides

What is the value of x if 2x + 23 = 90?

• 33.5

• 45

• 90

• 67

In a right angle, if one angle is 19 degrees, what is the sum of the other two angles?

• 90 degrees

• 71 degrees

• 180 degrees

• 161 degrees

If two angles are complementary and one is 30 degrees, what is the measure of the other angle?

• 120 degrees

• 60 degrees

• 30 degrees

• 90 degrees

What is the boundary point for the inequality -8x + 6 > -30?

• 4.5

• 3.75

• 6

• 5

How long does it take to run 1 kilometer if a runner completes a 5 km race in 31.5 minutes?

• 8.3 minutes

• 7.3 minutes

• 6.3 minutes

• 5.3 minutes

If Jada walked 4 more miles than Elena, and Lynn walked 2 more miles than Jada, how many miles did Lynn walk if the total is 37 miles?

• 9 miles

• 13 miles

• 17 miles

• 15 miles
