From the figure, let's find the missing measures.

• m∠e

Angle e is vertically opposite to the measure 66°

Applying the vertical angles theorem, both angles are congruent.

Thus, we have:

e = 66°

• m∠f:

To find the measure of angle f, apply the angles on a straight line theorem.

Angles on a straight line are supplementary ans supplementary angles sum up to 180 degrees.

Angle F and angle e are on a straight line.

Thus, we have:

m∠e + m∠f = 180

m∠f = 180 - m∠e

m∠f = 180 - 66

f = 114°

• m∠d

Angle d is a right angle. Thus, the measure of angle d is 90 degrees.

d = 90°

ANSWER:

• d = 90,°

,

• e = 66,°

,

• f = 114°

Hatshy [7]

Answer:

14.1 cm

Step-by-step explanation:

first find the base diagonal :

base di = Square root (8^2 + 6^2) = 10cm

so,

diagonal = Square root (10^2 + 10^2) = 14.1 cm (ANS)

Answer:

Scenario 1 represents a greater speed

Step-by-step explanation:

scenario 1 - find equation of line on graph to compare

- use the points given to find the slope

rate = slope = (y2-y1)/(x2-x1) = (240-60)/(4-1) = 60

y intercept = 0

line equation -> y = 60x

for every mile, 60 miles are traveled

scenario 2 - interpret the equation

for every mile, 50 miles are traveled

Scenario 1 represents a greater speed
