The given equation is:
Just multiply both numerators and both denominators respectively, with the bar line still between them. So, it becomes
Then you factor out the equations:
Simplify terms by dividing them. The negative sign and 3 cancels out. The answer would be:
An arc of a circle has the same measure as the central angle that intercepts it.
Central angle 1 intercepts arc AB.
The measure of central angle 1 is the same as the measure of angle AB.
The measure of arc AB is 30 deg.
Answer:
m-1: 31 degrees & m-4: 149 degrees
Step-by-step explanation:
we can start with im very bad at explaining but will try my best.
Step 1:
look at what you're given and remember the rules and principles of finding angles. so were given m-6. when having parallel lines with a perpendicular line the opposing side of the intercept will be the same. meaning that if m-6 is 149 then its opposing side, m-8, will have the same degree. but we know that with straight lines are 180 degrees so now that we have that out of the way we can move to step 2
Step 2:
you have the given and the rules to go with, so now we will begin to apply it. like i was saying a line is 180 degrees, and when we put a line through that we end up having different degrees. although theres an intercept the line is still 180 degrees. so to find the aligning angle we just have to subtract the given angle by our own knowledge.
180-149=31 this aligns with everything in this. there are only 2 angles necessary. 149 and 31, all we have to do now is plug it in.
M-5: 31 degrees
m-6: 149 degrees
m-7: 31 degrees
m-8: 149 degrees
Step 3:
all those annoying angles we just got through, guess what, all you have to do is apply those same angles with m1-m4
M-1: 31 degrees
M-2: 149 degrees
M-3: 31 degrees
M-4: 149 degrees
Answer:
B) The triangles are similar and have the same ratios for the height to the base . The slope of the line is .
Step-by-step explanation:
The triangles share the ratio , and the slope of . This narrows down the options to either A or B. But, the difference between the options are the words "similar and congruent." Congruent means that the triangles are exactly the same shape and size. Similar means that they share a shape but are different sizes. The triangles are similar.
Hope it helps!
