in triangle DEF, the measure of angle Eis 30 and the measure of angle F is 45. What is the measure of angle D?

angke D = 105°

Step-by-step explanation:

All triangles add up to 180°. 30+45=75 180-75=105

1010: 3030

is it i think

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.
