All three sides always add up to 360 so add the given measures and subtract it from 360 and that would give you your answer.
Answer:
-1/2 or -0.5
negative half
Step-by-step explanation:
slope of regular line= (y1-y2) / (x1-x2)
(27-3) / (4 - -8)
24 / (4+8)
24 / 12 = 2
the slope of a perpendicular line is the negative reciprocal
the negative reciprocal of positive 2/1 (2 as a fraction) is:
negative half: -1/2 or -0.5
Answer:
40
Step-by-step explanation:
The value of y from the diagram is 9
<h3>Similar shapes</h3>
From the given figure, the shapes are similar, using the similarity theorem of triangles, you ill have;
6/10 = y/15
Cross multiply
10y = 15* 10
10y = 90
y = 90/10
y = 9
Hence the value of y from the diagram is 9
