Answer:
272cm squared
Step-by-step explanation:
figure a, a traingle... to find area formula is
1/2×b×h
1/2×18×17
153
figure b, it's rectangle.so length×width
=7×17
=119
area of the shape=153+119
=272cm squared
Answer:
method 2 use the radians sector area formula
Answer:
The answer to this is 65
Step-by-step explanation:
20 divide by 4/13
Answer:
CD = 20°
Step-by-step explanation:
arc FA = arc CD because <ABF = <CBD (vertical angles)
Given <ABF = 20° so <ABF = <CBD = 20°
The central angle is also known as the arc's angular distance
so arc CD = <CBD = 20°
From the table,
P(selecting a 3) = 0.15
which means that,
P(not a 3) = 1 - P(selecting a 3)
P(not a 3) = 1 - 0.15
P(not a 3) = 0.85
Answer is 0.85
