In the first figure we have an angle that subtends a diameter. Those are always right angles, so
Answer: x=90 degrees
In the second figure we have to notice that the measure of arcs and central angles are interchangeable -- the measure of an arc is its central angle.
The units are implicitly degrees; the 10 should say 10°
These are supplementary angles so they add to 180°
3x + (7x + 10) = 180
10x = 170
x = 17
Answer: x=17
17° would be more accurate but the units are a bit ambiguous here so I'll leave it.
Answer:
Step-by-step explanation:
the 2nd one
Bike to work: d=16*t
ride home: d = 27*.4 =10.8
solve for t
10.8 = 16*t
t = 10.8/16
0.7 of an hour
I think you forgot to attach the tree diagram along with the question. I am answering the question based on my research. "Writing the results from a choice of 2 types of bread, 2 meats, and 2 cheeses" is the one description that <span>matches the sequence of events shown in the tree diagram below. The correct option is option "A".</span>
