[Help asap, will mark brainliest when it allows me] Find the missing angle measures in the following diagram. First drop down answer choices: 140, 75, 105.
Second drop down answer choices: 100, 140, 40.
Third drop down answer choices: 65, 40, 75.

Angle k= 105

Angle n= 40

Angle m= 65

m∡k = 105°

m∡n = 40°

m∡m = 65°

Step-by-step explanation:

m∡k = 105° because this angle forms a linear pair with a 75° angle

m∡n = 40° because this angle forms a linear pair with a 140° angle

m∡m = 65° because there are 180° in a triangle and one angle is 75° and the other angle is a vertical angle to angle 'n' which means they are equal

78.59 is the mean

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
