Answer:
Johnny and his family left home at 10:00.
Step-by-step explanation:
First, You add all of the minutes up,
45+20+10= 75
Then convert the minutes to hours,
75 mins = 1 hr and 15 mins.
Add the hours together,
1 hr + 2 hrs = 3 hrs
Then add minutes,
3 hrs and 15 minutes
Subtract 3 hrs and 15 mins from 13:15,
13.15 - 3.15 = 10:00
Your answer is:
Johnny and his family left home at 10:00.
Answer:
1)B:63°
2)A:59°
Step-by-step explanation:
1.ABC is a right triangle at C then angle ACB=90°(right angle)
Angle CAB=27°(see the given)
measure of the angles in any triangle is 180°
then angle CBA=
measure of all the angles - (measure ACB+measure CAB)
=180°-(90°+27°)
=63°
2. Same explanation of angle B:
in the right triangle DEF: angle DEF=90°
angle D=31°(given)
Then measure of angle A=180°-(angle E + angle D)
=180-(90+31)=59°
Answer:
Step-by-step explanation:
4(5-2)+(-7)(0.5)
20-8+(-3.5)
12-3.5
8.5
Answer:
118 degrees
Step-by-step explanation:
Supplementary = sum of the angles equal 180 degrees
180 - 62 = 118
118 degrees is your answer
