Its 15 markers, at least i would assume
Answer:
exterior angles:
144°and 36°
126° and 54°
90° and 90°
Step-by-step explanation:
we know that each angle in a triangle adds up to 180°.
so,
2x+3x+5x=180
10x=180
x=180/10
x=18
the interior angles are:
2x=36°
3x=54°
5x=90°
and explanation is provided to find the exterior angles above.(sorry for the bad handwriting)
Answer:
11.)4.79mi
12.)8cm
13.)10.6km
14.)5.93
15.)2yd
16.)5.41in
17)2y
18)2m
19)11.8yd
20)4.51km
Step-by-step explanation:
11.)15.8x2=31.6 31.6/6.6=4.79
12.)64/8=8
13.)26x2=54 54/4.9=10.6
14.)8.6x2=17.2 17.2/5.93
15.)2/1=2
16.)29.2/5.4=5.41
17)4/2=2
18)10/5=2
19)139.2/11.8=11.8
20)20.3/4.5=4.51
Check the picture below.
let's recall that a straight-line has 180°, and that sum of all interior angles in a triangle is also 180°.
Answer:
it's A cus i made a good grade so A is the right answer
