Answer:
30 mm
Step-by-step explanation:
1 centimeter (cm) is one hundredth of a meter
1 millimeter (mm) is one thousandth of a meter
Thus one cm is 10 times bigger, so 3cm = 30mm
It's B because the overall slope isn't changing, just the y value is changing.
Answer:
40degrees
Step-by-step explanation:
Find the diagram attached
Since the triangle ina semi circle is a right angle, hence <B = 90degrees
Also frm the diagram
<A + <B + <C = 180
<A + 90 + 50 = 180
<A + 140 = 180
<A = 180 - 140
<A = 40degrees
Hence the measure if m<BAC is 40degrees
Answer:
∠ ABC ≈ 137.9°
Step-by-step explanation:
Using the Cosine rule in Δ ABC
cos B =
with a = 89, b = 144, c = 65
cos B = = = , thus
B = ( - ) ≈ 137.9° ( to the nearest tenth )
