the answer to this problem is -4
Step-by-step explanation:
10 every 30 minutes means about one call every 3 minutes so in 6 minutes they should recieve 2 calls
B, D, and E are all correct. The line is coinciding.
I believe it is option 2, sorry if incorrect
m<1=23
m<2=90
m<3=67
m<4=113
m<5=67
the square means it is 90° so 2 is 90°.
all of the angles combined equals 360 so.
360-67-90= 203
since there is a straight line splitting down the middle. m<4=180-67=113
so m<4=113
now you would go 360-67-113-90=90 so
m<1 + m<3 =90
180-90-67=23.
m<1=23
360-67-23-90-113=67
m<3=67
