B,D is the answer for your question
Answer:
Step-by-step explanation:
1) Given figure is a parallelogram
Area = 144 cm²
base * altitude = 144
16 * x = 144
x =144/16
x = 9 cm
2)2) Trapezium
Area = 
; {a and b are parallel sides of trapezium}
( 37 +27 /2) * x = 480 cm²
64/2 * h = 480
32 * h = 480
h = 480/32
h = 15 cm
<span>The correct answer is 0.385.
Explanation<span>:
Decimals deal with powers of 10, such as 10, 100, 1000, etc. We can change this to a power of 10 by dividing both top and bottom by 2; this will give us 100 in the denominator.
77/2=38.5, so we have 38.5/100.
Dividing by 100 is the same as moving the decimal two places to the left, so we have 0.385.</span></span>
Answer: <em>50°</em>
Step-by-step explanation:
<em>Since angle 3 is in a right triangle we can assume one angle is 90°</em><em> </em><em>and then the other missing angle will be 40°</em>
<em>Because you take 180°-140°(the angle next to it) which will equal 40°</em>
<em>Now every triangle must add up to 180°</em>
<em>so lets take the angles we have now</em>
<em>90° +40°=130°</em>
<em>now take that 130°</em>
<em>180°-130°=</em><em>50°</em>
<em>Now check your work</em>
90°+40°+50°=180°
Angle 3 is 50°
